On some devices, the button driver allows a "software poweroff" by long-
pressing a certain key. This behavior is inconvnient when that button needs
to be held down for other purposes, such as moving the cursor in rockpaint
or sgt-untangle.
This patch allows selectively disabling the software poweroff (enabled by
default) from both core and plugin code.

No targets are enabled, but the hosted Hiby-based targets could have this
feature enabled if they weren't so buggy:
* No generic way to determine wakeup reason under Linux
* No generic way to be asynchronously notified if the alarm is
triggered when we're already awake
* Shutting down may clobber RTC wakeup (driver/etc dependent)
* Rocker's kernel's RTC driver has some 24h clock and timezone-related
issues.
So, the infrastructure is arguably useful, but the only applicable
hardware I have is pathologically brain-dead.

on timer_unregister callbacks are not removed
It seems (at least on the Rocker) timers continue to fire (for a bit??)
Now we store the registered callback in the sigev structure and check
that the callback matches the one registered when the timer is created.
This should stop the possible case of a new timer getting spurious callbacks
We also now NULL the callbacks on un-register which should stop the segfaults
Added some notes to timer.c and timer.h

Gives us the lowest HW sample rate that's >= 22KHz.
Needed because some targets that don't support 22K support 11K or 8K, so
HW_SAMPR_MIN will give us much lower quality than is acceptable.
Take advantage of this new macro in the SDL, MIDI, and MIKMOD plugins,
and implement a crude "fast enough" test to enable higher sample rates
on more capable targets.

Allow user to select cpu undervolt
There have been quite a few issues across the SANSA AMS line related
to CPU undervolting while most players show greatly increased runtime
some crash.
Rather than constanly upping the voltage we now have a
setting with a safe value for all players and the option for lower voltages
I plan to add a few other options here later such as disk
timings and maybe some other clocks/experimental settings
Added: Disk Low speed option for AS3525v2 devices cuts
frequency to 12 MHz from 24 MHz
Added: Disk Low speed option for AS3525v1 devices cuts
frequency to 15.5 MHz from 31 MHz
Added: I2c Low Speed AS3525 devices, should be bigger improvement for v1 devices
Fixed: Debug menu for AS3525v2 No SDSLOT frequency,
Showed IDE freq though it is unused
Added: DBOP and SSP underclocking affects display on v1/v2 respectively
Fixed: debug menu now has SSP frequency, and SSP_CPSR
Update: made settings menu more generic
Update: cleaned up code
Added: Clip v1 & Fuze v1 didn't have HAVE_ADJUSTABLE_CPU_VOLTAGE.
not sure why but, waiting on testing to confirm
Added: C200v2 and E200v2 devices and HAVE_ADJUSTABLE_CPU_VOLTAGE.
Fixed: v1 devices don't like display timing set lower (dbop)
v1 devices don't have a divider set for ssp (causes divide by 0)
Fixed: ClipZip display lags with Max SSP divider changed from 0xFE to 0x32
Fixed: v1 devices didn't work properly with highspeed sd cards
Added code from http://gerrit.rockbox.org/r/#/c/1704/
Added powersave and IDE interface enable/disable
Added: V2 devices now have powersave enabled on sd interface
Update: cleaned up code, lang defines, added manual entries
Update ssp clock mechanism added calculated ssp divider to clipzip
Update turn display clock off when clip+ turns off display

Instead of checking ticks, set a sticky dirty flag that indicates

accurate readout without actually reading the RTC until it changes.
The implementation should atomically read the flag and clear it.

Adds the ability to load firmware from other drives on MULTIVOLUME targets
Mihail Zenkov <mihail.zenkov@gmail.com> had posted a hard coded patch
to allow this on several Sansa players, I made it more universal
Redirect file rockbox_main.<name> should placed in root of
drive you would like to be main, if this file empty or there a single
slash '/' firmware will be loaded from /.rockbox in root of this drive
If instead a /<*DIRECTORY*> is supplied in rockbox_main.<name> then
firmware will be loaded from /<dir>/.rockbox/
NOTES*
The directory can have multiple levels however..
leading slash MUST be included
trailing slash can be omitted
(eg. /test/.rockbox would be simply '/test' in the redirect file)
Redirect file will not work on internal drive (whatever is default boot drive)
Volume with the highest index containing redirect file will be loaded
first.
Firmware file is checked for boot data region, if missing, firmware
image will not be loaded.
On failure or if no redirect file is found load will fallback to
internal drive
Currently only Sansa Fuze+, Sansa Clip+,
Sansa Clip Zip, Sansa Fuzev2, and Sansa Fuzev1 are implemented.
Players (with HAVE_MULTIVOLUME)
will need #define HAVE_BOOTDATA and #define BOOT_REDIR "rockbox_main.<name>"
added to their config file
boot_data is implemented in crt0.s file (See g#1552)
ARM and IMX233 have aleady been implemented
Once these conditions are met <HAVE_MULTIBOOT> will be defined by config.h
Partitions on the drives are able to have a redirect as
well.

* Editing a bunch of drivers' thread routines in order to
implement a new feature is tedious.
* No matter the number of storage drivers, they share one thread.
No extra threads needed for CONFIG_STORAGE_MULTI.
* Each has an event callback called by the storage thread.
* A default callback is provided to fake sleeping in order to
trigger idle callbacks. It could also do other default processing.
Changes to it will be part of driver code without editing each
one.
* Drivers may sleep and wake as they please as long as they give
a low pulse on their storage bit to ask to go into sleep mode.
Idle callback is called on its behalf and driver immediately put
into sleep mode.
* Drivers may indicate they are to continue receiving events in
USB mode, otherwise they receve nothing until disconnect (they
do receive SYS_USB_DISCONNECTED no matter what).
* Rework a few things to keep the callback implementation sane
and maintainable. ata.c was dreadful with all those bools; make
it a state machine and easier to follow. Remove last_user_activity;
it has no purpose that isn't served by keeping the disk active
through last_disk_activity instead.
* Even-out stack sizes partly because of a lack of a decent place
to define them by driver or SoC or whatever; it doesn't seem too
critical to do that anyway. Many are simply too large while at
least one isn't really adequate. They may be individually
overridden if necessary (figure out where). The thread uses the
greatest size demanded. Newer file code is much more frugal with
stack space. I barely see use crack 50% after idle callbacks
(usually mid-40s). Card insert/eject doesn't demand much.
* No forcing of idle callbacks. If it isn't necessary for one or
more non-disk storage types, it really isn't any more necessary for
disk storage. Besides, it makes the whole thing easier to implement.

I'm not sure all the situations it affects, to be honest. The fix
aimed to address the strange symptom here:
http://forums.rockbox.org/index.php/topic,50793.0.html
It turns out that ringbuf_add_cross was used when handles were
butted up against one another with the first parameter equal to
the last, which it interprets as being an empty case when it should
be interpreted as full in the context it was used. To fix this,
introduce full/empty variants of ringbuf_add_cross and ringbuf_sub
and use them at the appropriate time.
The other way to address the problem is ensure there's always at
least a space byte between the end of one handle and the start of
another but this make the code a bit trickier to reason about than
using additional function variants.
bufopen() may yield after creating a handle and so do some more
locking so that the buffering thread doesn't mess things up by
moving anything or not seeing the yet-to-be linked-in allocation.
Add alignof() macro to use proper method to get alignment of
struct memory_handle. That should be useful in general anyway.
It's merely defined as __alignof__ but looks nicer.

* Remove unused bits like the radio event and simplify basic
radio interface. It can be more self-contained with rds.h only
required by radio and tuner code.
* Add post-processing to text a-la Silicon Labs AN243. The chip's
error correction can only do so much; additional checks are highly
recommended. Simply testing for two identical messages in a row
is extremely effective and I've never seen corrupted text since
doing that, even with mediocre reception.
Groups segments must arrive in order, not randomly; logic change
only accepts them in order, starting at 0.
Time readout was made a bit better but really we'd need to use
verbose mode and ensure that no errors were seen during receiving
of time and more checks would be need to have a stable PI. The
text is the important bit anyway.
* Time out of stale text.
* Text is no longer updated until a complete group has been
received, as is specified in the standard. Perhaps go back to
scrolling text lines in the radio screen?
* Add proper character conversion to UTF-8. Only the default G0
table for the moment. The other two could be added in.
* Add variants "RDS_CFG_PROCESS" and "RDS_CFG_PUSH" to allow
the option for processed RDS data to be pushed to the driver and
still do proper post-processing (only text conversion for now for
the latter).

The implementation is not very complicated but there are a few things worth
noting. There was a previous "speaker enable" setting but it was a boolean.
I decided to replace it with a choice setting that has 2 options (on, off)
if headphones cannot be detect on this target, or 3 options (on, off, auto)
if we can detect headphones. This will break the old setting on target that
cannot detect jack but it makes the code more uniform and avoid maintaining
two settings with more #ifdef. The third option (auto) uses the LANG_AUTO
text, which I think is clear enough (disable speaker on jack plug).
In order to avoid code duplication (both in apps and firmware), I decided to
keep the audiohw_enable_speaker function as-is: it takes a boolean and doesn't
care about the speaker policy. I introduced a new audio_enable_speaker that
takes directly the mode (which follows the setting encoding): 0=off, 1=on
and 2=auto. This way one calls audio_enable_speaker and it changes the speaker
once to reflect the request mode. The apps code then uses this function in the
places where it makes sense: on setting load, setting change and jack (un)plug
event.

1. Slightly revised and regularized internal interface. Callback is used
for read and write to provide completion signal instead of having two
mechanisms.
2. Lower overhead for asynchronous or alterate completion callbacks. We
now only init what is required by the transfer. A couple unneeded
structure members were also nixed.
3. Fixes a bug that would neglect a semaphore wait if pumping the I2C
interrupts in a loop when not in thread state or interrupts are masked.
4. Corrects broken initialization order by defining KDEV_INIT, which
makes kernel_init() call kernel_device_init() to initialize additional
devices _after_ the kernel, threading and synchronization objects are
safe to use.
5. Locking set_cpu_frequency has to be done at the highest level in
system.c to ensure the boost counter and the frequency are both set in
agreement. Reconcile the locking inteface between PP and AMS (the only
two currently using locking there) to keep it clean.
Now works fine with voltages in GIT HEAD on my Fuze v2, type 0.
Previously, everything crashed and died instantly. action.c calling
set_cpu_frequency from a tick was part of it. The rest may have been
related to 3. and 4. Honestly, I'm not certain!
Testing by Mihail Zenkov indicates it solves our problems. This will
get the developer builds running again after the kernel assert code
push.

The function is neither reentrant nor ISR callable. Instead of
using a ticked-based timeout, have the button driver provide the
unboost after a delay when waiting for a button.
HAVE_GUI_BOOST gets immediate boost after dequeuing any message,
otherwise the queue has to have at least three messages waiting
for it to trigger a boost-- essentially the behavior that existed
but now combined in one place.

Playlist dircache references should be back in working order.
Reenabling dircache references in the database ramcache is not
yet done as it requires quite a bit of rework. Otherwise, the
database in RAM is functional again.
Some buffer compatibility changes have been made for database

The file system rework introduced incompatibility between dircache
and the tagcache ramcache and playlist dircache path caching. This
update makes changes to filesystem code to reintegrate all that.
It also fixes a couple bugs that were found when vetting all the
code. The filestream cache was being reset without regard to
the stream even if it was shared in write mode (made work of
.playlist_control). Better handling of unmounting gives files a
better go at force-closing them without risk to disk integrity.
Did some miscellaneous pedantic changes. Improved efficiency of
testing a file's existence (a little) since the path parser will
be shared between file code and parsing for the sake of finding
dircache references, not duplicated as before.
This commit doesn't reenable said items just for the sake of
keeping changes separate and related.
Plan for the next is to enable dircache again for the playlists
(easy peasy) and reenable tagcache ramcache but *without* the
dircache path caching because it's rather substantial to change
in itself. The ramcache will still function without dircache.

Some changes in behavior were made with filesystem code commit
for the sake of compatibility that changed expected behavior.
* Restore substitution of drive spec in fully-qualified DOS paths
with the playlists's volume spec (or root on univolume targets).
Drive-relative paths of the form "c:foo" (no separator after
':') will be treated as purely relative.
* Restore old behavior of preserving leading whitespace in the
source path and trimming only trailing tabs and spaces.
* Multivolume: Volume substition on fully-qualified UNIX/RB paths
has NOT been reintroduced (and perhaps wasn't intended in the
first place). They will not be modified because there is no
ambiguity to resolve. Doing so would prevent a playlist on
external storage from referencing a file on main storage without
qualifying it with "/<0>...".
* Plain relative paths are and always have been interpreted as
relative to the location of the playlist.

The ZEN X-Fi Style doesn't have an updater like the other stmp targets but at
least the stub enables rebooting to the OF.

The old code made the setting appear as 0dB, 1.5dB, 3dB and 4.5dB when
in fact it is 0dB, 3dB, 4.5dB and 6dB. This commit clarifies the code and
also fix this at the same time. This imx233 3D enhancement is complete crap anyway
but now you can satisfy yourself with 6 dB of pure crap, clearly an enhancement.

Everytime I use it, I get highly confused because it's complicated and
undocumented. The code is spread all over the place and some targets clearly
use incorrect values. This is the first step of a series to cleanup audio settings
and document it properly.

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

- Some rewrite with the intent to get ride of these random errors
appearing on some builds/devices (not much noticeable on RB but
can ruin bootloader builds).

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
-------- ------------- ------ --- --------- ------- -------
as3525v2 sansaclipplus 2.60a Yes Dedicated 0x535 4/4
sansaclipv2
sansaclipzip
sansafuzev2
s5l8701 ipodnano2g 2.20a Yes Shared 0x500 4/5
s5l8702 ipod6g 2.60a Yes Dedicated 0x820 7/7
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.

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.

PMU interrupts are used to detect USB Vbus, wall adaptor, accessories
and holdswitch. A thread is needed to poll the PMU throught I2C, ATM
it does nothing but showing the state of the inputs on the HW debug
menu, funcionallity for each individual input will be added in next
patches.

Do not rely on a bootloader initializing the HW, RB initializes
and configures GPIO, I2C, and PMU at startup.

When the bootloader starts, most of HW never has been initialized.
This patch includes all code needed to perform the preliminary
initialization on SYSCON, GPIO, i2c, and MIU.
The code is based on emCORE and OF reverse engineering, ported to
C for readability.

The write buffer size is undefined to use the default 24Kb. size
defined (and recomended) in usb_storage.c, the read buffer size is
also decremented to 24 Kb. USB sequential read and write benchmarks
using diskdump are now 8-9% faster.

When the bootloader starts only IRAM is available, the first task is to
ask the PMU to verify if the iPod has previously been hibernated by OF.
Due to memory limitations, the kernel cannot be used on this stage.
This patch modifies I2C and PMU low level functions to not to depend
on kernel (removes mutexes, and uses HW timer instead of current_tick),
actual kernel functions are modified to be 'mutexed' wrappers of the new
functions.

Add UART support for s5l8700/1 using the UC870X UART controller,

- Small rework on the UC8702 UART controller to make it compatible with
other s5l870x SOCs. Files moved and renamed, many conditional code
added to deal with capabilities and 'features' of the different CPUs.
- A couple of optimizacions that should not affect the functionality.

Voltage is reduced when the CPU is unboosted, resulting in a large
reduction in power consumption. In analogy with the AMSv1 voltage
scaling code (currently disabled due to problems with SD cards),
I have defined a config file option to enable/disable it.

Some old code made the assumption that CONFIG_CPU == AS3525v2 if and only if
HAVE_AS3543, which is not true on targets like the Samsung YP-R0. This fixes
several issues on such targets like a huge volume gap between -39dB and -40dB
and a volume artificially capped at -72dB instead of -82dB.

Voltage scaling is not yet enabled, but will follow once we are sure
these changes are stable. Preliminary testing suggests a large
increase in battery life, which will be further improved by voltage
scaling. Patch by Mihail Zenkov with help from myself and others on
