5c9688961e Implement a much more capable vuprintf()
New support as well as some buggy support fixed.

Still no floating point support if ever that would be desired.

Support (*):
* Flags: '-', '+', ' ', '#', '0'

* Width and precision: 'n', '.n', '*' and '.*'

* Length modifiers: 'hh', 'h', 'j', 'l', 'll', 't', 'z'

* Radix: 'c', 'd', 'i', 'n', 'o', 'p/P', 's', 'u', 'x/X'

(*) Provision exists to switch lesser-used stuff on or off or when
certain functionality isn't desired (bootloader?). The compulsory
radixes are everything but 'o', 'n', 'p/P' and 'x/X' with length
modifiers being optional. The default setup is 'l', 'z', 'c', 'd',
'p/P', 's', 'u', 'x/X'.

* Move fdprintf() to its own file. It was in a strange place.

* Make callers compatible and fix a couple snprintf() bugs while
at it.

Could smush it down in size but I'm gonna get over the binsize
neurosis and just the let optimizer do its thing.

0fe7b8becf nwzlinux: add support for radio
None of the Sony up to A15 seem to support RDS (they use either Si4702 or Si4708),
thus I did not add any code to support RDS.

e9f7385bdf Samsung YP-Z5: keypad adaption to the new button API
After compiling the ypz5 target, I have discovered that the keypad
system was refusing to compile, due to a much newer button API.
This patch adapts the target to the current imx233 implementation.
Additonally, some ADC button values have been re-adjusted.

2220a4b695 Improve imx31 interrupt code for PMIC and GPIO
Fix stuff that was bugging me about the way I did it at first.

While messing around I found RDS code wasn't masking its GPIO
ISR as it should, which might lead to two different interrupts
messing with the static data.

a983859291 imx233: add capability to boot OF or updater instead of Rockbox
This commit adds the necessary code in the dualboot stub (bootloader) to
let rockbox control the boot process. In particular, rockbox can now choose
if the next boot will be normal (boot rockbox or OF on magic key), to OF
or to updater.

The intents (to be added in follow-up commits) are:
1) Let the user more easily reboot to the OF. On some targets it is not trivial,
especially in USB mode.
2) Automatically reboot to updater when the user drop firmware.sb at the root
of the drive (currently, the user needs to do that in OF USB mode)
3) Document this OF magic

5e305d35c9 Introduce new USB driver for Synopsys DesignWare USB OTG core.
Based on g#844 and g#949, it is intended as a replacement for the
current s3c6400x USB driver.

The DesignWare USB OTG core is integrated into many SoC's, however
HW core version and capabilities (mainly DMA mode, Tx FIFO mode,
FIFO size and number of available IN/OUT endpoins) may differ:

CPU       targets        HW ver  DMA  NPTX FIFO  FIFO sz  #IN/OUT

          ipodnano3g
s5l8720   ipodnano4g     ?       ?    ?          ?        ?

Functionality supported by this driver:
- Device mode, compatible with USB 1.1/2.0 hosts.
- Shared FIFO (USB_DW_SHARED_FIFO) or dedicated FIFOs.
- No DMA (USB_DW_ARCH_SLAVE) or internal DMA mode.
- Concurrent transfers: control, bulk (usb_storage, usb_serial) and
  interrupt (usb_hid).

Actually this driver is not used by any CPU, it will be enabled for
each individual CPU/target in next patches.

b2afd931e2 fuze+: rewrite touchpad driver
The old driver was bad in many respect, it had some race conditions, it was
using a thread to serialize transfers because of the legacy i2c interface.
It also had huge latency (typically 50ms but delays up to 300ms can happen),
thus some presses were missed.
The new driver takes advantage of the new i2c driver to do everything
asynchronously. It also does not need a thread anymore because queueing
ensures proper serialization. It provides much better and reliable latency
(typically ~2ms).
Also fix the debug screen which was horribly broken. The new screen also
displays the deadzones.

f753b8ead1 iPod Classic: s5l8702 clocking rewrite+documentation
This is a rewrite of the clocking section, the resulting system
frequencies are the same as the current git version.

This pàtch uses fixed FClk and just one register is written to switch
all system frequencies, it needs less steps than the current git
version to reach the desired frequency, so it is faster and safer.
Includes functions to step-up/down over a table of predefined set of
frequencies.

The major difference is that Vcore is decreased from 1050 to 1000 mV.

See clocking-s5l8702.h for more information.

67b4e7f958 iPod Classic: use new PL080 DMA driver
This patch uses the new pl080 DMA driver for I2S playback and LCD
update. I have tried to be as fiel as possible to the current
behaviour, algorithms and configurations are the same, but using
the new driver. Other modifications:

Playback:

 - CHUNK_SIZE is decreased from 42988 to 8188 bytes, it does not
   affect normal playback (block size 1024), was tested using
   metronome (block size 46080). This change is needed because the
   new code commits d-cache range instead of commiting the whole
   d-cache, maximum time spent commiting the range should be
   limited, CHUNK_SIZE can be decreased even more if necessary.

 - pcm_play_dma_start() calls pcm_play_dma_stop() to stop the
   channel when it is running (metronome replays the tick sound
   without stopping the channel).

 - pcm_play_dma_get_peak_buffer(): same as actual SVN function but
   returns samples count instead of bytes count.
   TODO: AFAIK, actually this function is not used in RB. Not tested,
   but probably this function will fail because it returns pointers
   to the internal double buffer.

LCD update:

 - suppresses lcd_wakeup semaphore and uses yield()

d6ee2c9eaf iPod Classic: introduce PL080 DMA controller driver
Motivation:

 This driver began as a set of functions to help to test and
 experiment with different DMA configurations. It is cumbersome,
 time consuming, and leads to mistakes to handle LLIs and DMA
 registers dispersed along the code.

 Later, i decided to adapt an old DMA queue driver written in the
 past for a similar (scatter-gather) controller, all task/queue
 code is based on the old driver.

 Finally, some cleaning and dmac_ch_get_info() function was added
 to complete RB needs.

Description:

 - Generic, can be used by other targets including the same
   controller. Not difficult to adapt for other similar
   controllers if necesary.

 - Easy to experiment and compare results using different
   setups and/or queue algorithms:

   Multi-controller and fully configurable from an unique place.

   All task and LLI management is done by the driver, user only
   has to (statically) allocate them.

 - Two queue modes:

   QUEUE_NORMAL: each task in the queue is launched using a new
   DMA transfer once previous task is finished.

   QUEUE_LINK: when a task is queued, it is linked with the last
   queued task, creating a single continuous DMA transfer. New
   tasks must be queued while the channel is running, otherwise
   the continuous DMA transfer will be broken.

   On Classic, QUEUE_LINK mode is needed for I2S continuous
   transfers, QUEUE_NORMAL is used for LCD and could be useful
   in the future for I2C or UART (non-blocking serial debug) if
   necessary.

 - Robust DMA transfer progress info (peak meter), needs final
   testing, see below.

Technical details about DMA progress:

 There are comments in the code related to the method actually
 used (sequence method), it reads progress without halting the
 DMA transfer. Althought the datasheet does not recommend to do
 that, the sequence method seems to be robust, I ran tests calling
 dmac_ch_get_info() millions of times and the results were always
 as expected (tests done at 2:1 CPU/AHB clock ratio, no other
 ratios were tried but probably sequence method will work for any
 typical ratio).

 This controller allows to halt the transfer and drain the DMAC
 FIFO, DMA requests are ignored when the DMA channel is halted.
 This method is not suitable for playback because FIFO is never
 drained to I2S peripheral (who raises the DMA requests). This
 method probably works for capture, the FIFO is drained to memory
 before halting.

 Another way is to disable (stop) the playback channel. When the
 channel is disabled, all FIFO data is lost. It is unknown how much
 the FIFO was filled when it was cleared, SRCADDR counter includes
 the lost data, therefore the only useful information is LINK and
 COUNT, that is the same information disponible when using the
 sequence method. At this point we must procced in the same way as
 in sequence method, in addition the playback channel should be
 relaunched (configure + start) after calculating real SRCADDR.

 The stop+relaunch method should work, it is a bit complicated,
 and not valid for all peripheral FIFO configurations (depending
 on stream rate). Moreover, due to the way the COUNT register is
 implemented in HW, I suspect that this method will fail when
 source and destination bus widths doesn't match. And more
 important, it is not easy to garantize that no sample is lost
 here or there, using the sequence method we can always be sure
 that playback is ok.

609cde9468 iPod Classic: s5l8702 GPIO interrupt controller.
This patch implements a simple API to use the external interrupt
hardware present on s5l8702 (GPIO interrupt controller). This
GPIOIC has been fully tested using emcore apps.

Code is based on openiBoot project, there are a few modifications
to optimize space considering we will only use two or three external
interrupts. The API compiles and works, but has been never used,
therefore probably will need some changes to the final version.

External interrupts are necessary for jack remote+mic controller
(see iAP Interface Specifiction: Headphone Remote and Mic System),
this controller is located at I2C bus address 0x72, there is a IRQ
line for remote button press/release events routed to GPIO E6. At
this moment, the functionallity of this controller has been
extensively tested using emcore, getting a lot of information about
how it works. Microphone is already working on RB, jack accessory
detection and button events are work in progress.

PMU IRQ line is also routed to GPIO F3, it signals many events:
holdswitch, usb plug, wall adapter, low battery... The use of PMU
interrupts is the orthodox way of doing things, at this moment
there is no work done in this direction, there are a lot of PMU
events and i think it is a matter of discursion what to do and how.

dbabd0d9c3 iBasso DX50/DX90: Major code cleanup and reorganization.
Reorganization

- Separated iBasso devices from PLATFORM_ANDROID. These are now standlone
  hosted targets. Most device specific code is in the
  firmware/target/hosted/ibasso directory.
- No dependency on Android SDK, only the Android NDK is needed.
  32 bit Android NDK and Android API Level 16.
- Separate implementation for each device where feasible.

Code cleanup

- Rewrite of existing code, from simple reformat to complete reimplementation.
- New backlight interface, seperating backlight from touchscreen.
- Rewrite of device button handler, removing unneeded code and fixing memory
  leaks.
- New Debug messages interface logging to Android adb logcat (DEBUGF, panicf,
  logf).
- Rewrite of lcd device handler, removing unneeded code and fixing memory leaks.
- Rewrite of audiohw device handler/pcm interface, removing unneeded code and
  fixing memory leaks, enabling 44.1/48kHz pthreaded playback.
- Rewrite of power and powermng, proper shutdown, using batterylog results
  (see http://gerrit.rockbox.org/r/#/c/1047/).
- Rewrite of configure (Android NDK) and device specific config.
- Rewrite of the Android NDK specific Makefile.

Misc

- All plugins/games/demos activated.
- Update tinyalsa to latest from https://github.com/tinyalsa/tinyalsa.

Includes

- http://gerrit.rockbox.org/r/#/c/993/
- http://gerrit.rockbox.org/r/#/c/1010/
- http://gerrit.rockbox.org/r/#/c/1035/

Does not include http://gerrit.rockbox.org/r/#/c/1007/ due to new backlight
interface and new option for hold switch, touchscreen, physical button
interaction.

Rockbox needs the iBasso DX50/DX90 loader for startup, see
http://gerrit.rockbox.org/r/#/c/1099/

The loader expects Rockbox to be installed in /mnt/sdcard/.rockbox/. If
/mnt/sdcard/ is accessed as USB mass storage device, Rockbox will exit
gracefully and the loader will restart Rockbox on USB disconnect.

Tested on iBasso DX50.
Compiled (not tested) for iBasso DX90.

0b5ad60c26 Introducing Targets iBasso DX50 & iBasso DX90
The port to for this two targets has been entirely developped by Ilia Sergachev (alias Il or xzcc). His source
can be found at https://bitbucket.org/isergachev/rockbox . The few necesary modifications for the DX90 port
was done by headwhacker form head-fi.org. Unfortunately i could not try out the final state of the DX90 port.
The port is hosted on android (without java) as standalone app. The official Firmware is required to run this port.
Ilia did modify the source files for the "android" target in the rockbox source to make the DX port work. The work I did
was to separate the code for DX50 (&DX90) from the android target.
On this Target Ilia used source from tinyalsa from AOSP. I did not touch that part of the code because I do not understand it.
What else I changed from Ilias sources besides the separation from the target "android":
* removed a dirty hack to keep backlight off
* changed value battery meter to voltage battery meter
* made all plugins compile (named target as "standalone") and added keymaps
* i added the graphics for the manual but did not do anything else for the manual yet
* minor optimizations

known bugs:
* timers are slowed donw when playback is active (tinyalsa related?)
* some minor bugs

Things to do:
* The main prolem will be how to install the app correctly. A guy called DOC2008 added a CWM (by androtab.info) to the
  official firmware and Ilia made a CWM installation script and a dualboot selector (rbutils/ibassoboot, build with
  ndk-build). We will have to find a way to install rockbox in a proper way without breaking any copyrights.
  Maybe ADB is an option but it is not enable with OF by default. Patching the OF is probably the way to go.
* All the wiki and manual

to build:
needed: android ndk installed, android sdk installed with additional build-tools 19.1.0 installed

./tools/configure
select iBasso DX50 or iBasso DX90
make -j apk

the content of rockbox.zip/.rockbox needs to be copied to /system/rockbox/app_rockbox/rockbox/ (rockbox app not needed)
the content of libs/armeabi to /system/rockbox/lib/ (rockbox app needed)

The boot selector is needed as /system/bin/MangoPlayer and the iBasso app as /system/bin/MangoPlayer_original. There
is also the "vold" file. The one from OF does not work with DX50 rockbox (DX90 works!?), the one from Ilia is necessary.

7d1a47cf13 Rewrite filesystem code (WIP)
This patch redoes the filesystem code from the FAT driver up to the
clipboard code in onplay.c.

Not every aspect of this is finished therefore it is still "WIP". I
don't wish to do too much at once (haha!). What is left to do is get
dircache back in the sim and find an implementation for the dircache
indicies in the tagcache and playlist code or do something else that
has the same benefit. Leaving these out for now does not make anything
unusable. All the basics are done.

Phone app code should probably get vetted (and app path handling
just plain rewritten as environment expansions); the SDL app and
Android run well.

Main things addressed:
1) Thread safety: There is none right now in the trunk code. Most of
what currently works is luck when multiple threads are involved or
multiple descriptors to the same file are open.

2) POSIX compliance: Many of the functions behave nothing like their
counterparts on a host system. This leads to inconsistent code or very
different behavior from native to hosted. One huge offender was
rename(). Going point by point would fill a book.

3) Actual running RAM usage: Many targets will use less RAM and less
stack space (some more RAM because I upped the number of cache buffers
for large memory). There's very little memory lying fallow in rarely-used
areas (see 'Key core changes' below). Also, all targets may open the same
number of directory streams whereas before those with less than 8MB RAM
were limited to 8, not 12 implying those targets will save slightly
less.

4) Performance: The test_disk plugin shows markedly improved performance,
particularly in the area of (uncached) directory scanning, due partly to
more optimal directory reading and to a better sector cache algorithm.
Uncached times tend to be better while there is a bit of a slowdown in
dircache due to it being a bit heavier of an implementation. It's not
noticeable by a human as far as I can say.

Key core changes:
1) Files and directories share core code and data structures.

2) The filesystem code knows which descriptors refer to same file.
This ensures that changes from one stream are appropriately reflected
in every open descriptor for that file (fileobj_mgr.c).

3) File and directory cache buffers are borrowed from the main sector
cache. This means that when they are not in use by a file, they are not
wasted, but used for the cache. Most of the time, only a few of them
are needed. It also means that adding more file and directory handles
is less expensive. All one must do in ensure a large enough cache to
borrow from.

4) Relative path components are supported and the namespace is unified.
It does not support full relative paths to an implied current directory;
what is does support is use of "." and "..". Adding the former would
not be very difficult. The namespace is unified in the sense that
volumes may be specified several times along with relative parts, e.g.:
"/<0>/foo/../../<1>/bar" :<=> "/<1>/bar".

5) Stack usage is down due to sharing of data, static allocation and
less duplication of strings on the stack. This requires more
serialization than I would like but since the number of threads is
limited to a low number, the tradoff in favor of the stack seems
reasonable.

6) Separates and heirarchicalizes (sic) the SIM and APP filesystem
code. SIM path and volume handling is just like the target. Some
aspects of the APP file code get more straightforward (e.g. no path
hashing is needed).

Dircache:
Deserves its own section. Dircache is new but pays homage to the old.
The old one was not compatible and so it, since it got redone, does
all the stuff it always should have done such as:

1) It may be update and used at any time during the build process.
No longer has one to wait for it to finish building to do basic file
management (create, remove, rename, etc.).

2) It does not need to be either fully scanned or completely disabled;
it can be incomplete (i.e. overfilled, missing paths), still be
of benefit and be correct.

3) Handles mounting and dismounting of individual volumes which means
a full rebuild is not needed just because you pop a new SD card in the
slot. Now, because it reuses its freed entry data, may rebuild only
that volume.

4) Much more fundamental to the file code. When it is built, it is
the keeper of the master file list whether enabled or not ("disabled"
is just a state of the cache). Its must always to ready to be started
and bind all streams opened prior to being enabled.

5) Maintains any short filenames in OEM format which means that it does
not need to be rebuilt when changing the default codepage.

Miscellaneous Compatibility:
1) Update any other code that would otherwise not work such as the
hotswap mounting code in various card drivers.

2) File management: Clipboard needed updating because of the behavioral
changes. Still needs a little more work on some finer points.

3) Remove now-obsolete functionality such as the mutex's "no preempt"
flag (which was only for the prior FAT driver).

4) struct dirinfo uses time_t rather than raw FAT directory entry
time fields. I plan to follow up on genericizing everything there
(i.e. no FAT attributes).

5) unicode.c needed some redoing so that the file code does not try
try to load codepages during a scan, which is actually a problem with
the current code. The default codepage, if any is required, is now
kept in RAM separarately (bufalloced) from codepages specified to
iso_decode() (which must not be bufalloced because the conversion
may be done by playback threads).

Brings with it some additional reusable core code:
1) Revised file functions: Reusable code that does things such as
safe path concatenation and parsing without buffer limitations or
data duplication. Variants that copy or alter the input path may be
based off these.

To do:
1) Put dircache functionality back in the sim. Treating it internally
as a different kind of file system seems the best approach at this
time.

2) Restore use of dircache indexes in the playlist and database or
something effectively the same. Since the cache doesn't have to be
complete in order to be used, not getting a hit on the cache doesn't
unambiguously say if the path exists or not.

981d028c09 Do some kernel cleanup
* Seal away private thread and kernel definitions and declarations
into the internal headers in order to better hide internal structure.

* Add a thread-common.c file that keeps shared functions together.
List functions aren't messed with since that's about to be changed to
different ones.

* It is necessary to modify some ARM/PP stuff since GCC was complaining
about constant pool distance and I would rather not force dump it. Just
bl the cache calls in the startup and exit code and let it use veneers
if it must.

* Clean up redundant #includes in relevant areas and reorganize them.

* Expunge useless and dangerous stuff like remove_thread().

533d396761 Add multi-reader, single-writer locks to kernel.
Any number of readers may be in the critical section at a time and writers
are mutually exclusive to all other threads. They are a better choice when
data is rarely modified but often read and multiple threads can safely
access it for reading.

Priority inheritance is fully implemented along with other changes to the
kernel to fully support it on multiowner objects.

This also cleans up priority code in the kernel and updates some associated
structures in existing objects to the cleaner form.

Currently doesn't add the mrsw_lock.[ch] files since they're not yet
needed by anything but the supporting improvements are still useful.

This includes a typed bitarray API (bitarray.h) which is pretty basic
for now.

a1842c04f9 lcd-24bit: Introduce a 24-bit mid-level LCD driver
With LCD driver all calculation will be performed on RGB888 and the hardware/OS
can display from our 24bit framebuffer.

It is not yet as performance optimized as the existing drivers but should be
good enough.The vast number of small changes is due to the fact that
fb_data can be a struct type now, while most of the code expected a scalar type.

lcd-as-memframe ASM code does not work with 24bit currently so the with 24bit
it enforces the generic C code.

All plugins are ported over. Except for rockpaint. It uses so much memory that
it wouldnt fit into the 512k plugin buffer anymore (patches welcome).

This driver will subsume the old button-lradc driver and support far more
options. It can sense LRADC channels, PSWITCH, GPIOs and it handles special
"buttons" like headphone insertion and hold detection. It also provides a
more natural description of the buttons using a target-defined table with some
macros to make it easy to read and write. It uniformely handles debouncing on
LRADC channels and PSWITCH.
