127e6bbfdd Add support for the NWZ-E350
Strangely it has the SAME encryption key as the E450. Either they didn't bother
changing it or more likely they have exactly the same internals and a slightly
different case.

eefc7c73e2 Fix some problems with playback crashing
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.

6db80020b4 Do some housekeeping with fat.h and SECTOR_SIZE
Many includes of fat.h are pointless. Some includes are just for
SECTOR_SIZE. Add a file 'firmware/include/fs_defines.h' for that
and to define tuneable values that were scattered amongst various
headers.

Remove some local definitions of SECTOR_SIZE since they have to be
in agreement with the rest of the fs code anyway.

(We'll see what's in fact pointless in a moment ;)

fc9695eb47 Improve radio RDS driver and framework
* 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).

1245c5fe61 Implement speaker enable/disable on jack (un)plug
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.

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.

783c77531c AMS: Return ascodec to interrupt-based I2C2 driver
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.

c6299b268d action.c must desist in calling set_cpu_frequency from a tick
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.

dc87e9e9f3 Selective Backlight/Advanced Softlock - Selective actions based on context
Selective backlight allows the user to choose actions that will not
enable the backlight when pressed.

Advanced softlock allows user to choose actions that  will not be
blocked by screenlock on devices without a hold button.

Both only occur in FM and WPS Contexts.

Update:
Back from the dead
-Cleaned up code, removed unnecessary calls, re-arranged last filter action
  timeout conditional to work in case last_filtered_action_tick was never set
-Added entries to the manual
-Fixed back button on some menus not activating backlight
-Made menus more intuitive, no actions selected now changes menu item to off.
-Added talk fuctionality.
-Added option to disable selective backlight while on external power.
-Rewrote backlight and softlock handling code to fix issue with scrollwheels
-Menu changed to have toggle(yes/no) and settings
-Optimized selective actions lookup
-Added option to disable notification of 'buttons locked' while softlocked
-Removed uneeded code, consolidated action lookup to single function
-Fixed incorrect name on selective softlock menu
-Added option to disable touch on touchscreen devices
-Fixed backlight on original screenlock without selective screenlock active
-Added text selection in mask_select for when show_icons is off
-Fixed voice in mask_select to speak if voice is defined instead of spelling
-Added more lang defines (play skip seek)
-Added option to disable unknown keys turning on backlight
-Fixed Conditional argument In wrong place causing players without
	backlight to fail to build
-Fixed Disable Unknown blocking detection of context change
-Fixed canceling menu didn't update new settings
-Added Autolock on backlight off
-Removed backlight_on_force from backlight.c, Now sets ignore next to false
	and uses backlight_on
-Cleaned up autolock code added strings to lang file
-Fixed issue where rapid presses would bypass softlock
-Removed old softlock code, Cleaned selective actions code
-Changed menu to match existing RB menus
-Fixed Backlight_on_Hold blocked by backlight_ignore_next
-Fixed ignore_next for ipod
-Fixed bug allowing context with softlock to bypass selective backlight
-Changed mask_select to no longer prompt for changes to be saved
-Changed menu names
-Added ignore timeout to allow ipod scroll wheel to work properly and other
 players to still work properly, removed some previous code including
 ignore_event
-Increased ignore timeout to prevent sd card accesses from interrupting action
 code and turning on backlight
-Changed Unknown action to unmapped action in menu, changed handling code
-Removed unneeded logic and variables for handling unfiltered actions
-Reverted unmapped action code to previous functionality
-Added manual entries (thanks JohnB)
-Removed elusive unhandled unicode character from manual, changed formatting slightly

Actions:
Volume,Play,Seek,Skip

Extras:
Disable unmapped actions
Disable selective backlight on external power
Disable touch during softlock on touchscreen devices
Disable softlock notifications (power button still notifies)
Autolock on backlight off

Method:
Adds a function to ignore backlight on next call
 If selected action occurs backlight is forced on,
 Filter_first_keypress stays intact.

Selective softlock allows selected actions through, bypasses the normal
 softlock routine.

ToDo:
DONE

previous commit (#1) has attribution for folder_select.c which mask_select
is based from.

16a9f84571 Reenable database ramcache and playlist dircache
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
commit because the dircache buffer can no longer be stolen, only
freed by an API call.

a931c76b3a Do some debug and preparatory work for ramcache and playlist
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.

5c6ccb43b5 Fix track formatting problems in playlist.c
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.

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

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.

98bd2231ec iPod Classic: introduce PMU interrupts
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.

3f17745930 iPod Classic: HW initialization for RB
Do not rely on a bootloader initializing the HW, RB initializes
and configures GPIO, I2C, and PMU at startup.

1aefd9ea41 iPod Classic: HW preliminary initialization for bootloader
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.
