The ZEN/X-Fi (STMP3700) don't handle memory frequency scaling really well, for
this reason we run it at a fixed frequency. That frequency was previously set
to 64Mhz because when the CPU run at its lowest frequency, we set the VDD voltage
to 0.975 V and on STMP3700, VDDD=VDDDMEM and this is too low to run EMI at 130Mhz.
This is not a good solution because under heavy load, running the EMI at 64Mhz
results in frame drops and a sluggish device. Thus we now run the EMI at 130Mhz
all the time now. To do so, increase the minimum VDD voltage to 1.275 V.
This may result is a decreased battery life on those targets but it will also
avoid all sorts of glictches and all the device to truly run at full speed.

One cannot call lradc_acquire in IRQ context. The solution is to reserve the
channel once at init. There is an additional complication on STMP3600 where
channel mapping is fixed.

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.

si4700_rds_process() should only be called on the rising edge of
RDSR since it now rejects segments out of sequence. Receiving the
same segment multiple times due to rapid polling is of course out
of sequence so do no more processing until RDSR bit cycles to
avoid repeatedly sending the same data instance.
I don't have the tools installed to test compile so there could be
typos. However, I tested on gigabeat-s with YPR0 setup copied over
and it fixed the issue with PS and RT.

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.

There's only a need to check every MAX_TINYNAME+1 bytes and that the
last character of the needed size 0xff in order to verify the size
of the block since the minimum indirectly-stored string is
MAX_TINYNAME+1.

When dircache scanning is happening in the background, the user
can shut down the device before it is complete. Then, reset_cache()
sets size to 0 before it is copied to last_size at the end of
build_volumes(). When saved last_size is zero, scanning happens in
the foreground during next startup.
Avoid shrinking the size if the build is suspended.

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 ;)

* 8 bits is enough to allow 260 character base names when five
bytes is the minimum indirect storage size (0..255->5..260).
* Don't truncate anything that's too long as that can lead to
bad behavior, simply don't include the offending entry in the
parent.
* Set the .tinyname flag to 1 by default to indicate that
the entry's name doesn't need freeing. Clear it only when
allocating indirect storage.
* Rename some things to help catch all instances

Moving binding from queued to resolved was messed up if it was the
first queued one and there were other resolved files open at the
time of resolving it.
Dircache info for a directory about to be recursively scanned should
be filled before opening it. Would only affect a directory if it
happened to be opening while it was being initialized.

These flags aren't stored for an open file because they're simply
actions for open() to take, corresponding to O_CREAT and O_EXCL.
Just pass the oflag argument along to the deeper call, with some
minor filtering.

* fmradio.c needs an implementation of tuner_get_rds_info() for the
sim (kill all the sims).

defined.

* 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).

If a volume root was open at the beginning of a build, its dircache
reference wouldn't be resolved on an already open volume root
directory because the call to do it was simply omitted. Nothing
horribly bad unless a root were opened at mount time and kept open
long term.

volume_onmount_internal() was being given the next volume to mount
instead of the one just mounted. Only dircache was being notified
for now, which always attempts to scan everything that needs to be
rebuilt, currently making the volume parameter value immaterial.
Put things in the right place and also set the disk sector
multiplier before notifying anybody of the new volume.

On Windows 64-bit, the size of long is 32-bit, thus any pointer to long cast is
not valid. In any case, one should use intptr_t and ptrdiff_t when casting
to integers. This commit attempts to fix all instances reported by GCC.
When relevant, I replaced code by the macros PTR_ADD, ALIGN_UP from system.h

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.

Running at 130MHz is unsafe since on those targets, we disable memory frequency
scaling because it is unstable. That leads to situation where cpu is running at
64MHz and VDD is at 1.050V. But on STMP3700, the EMI uses the VDD rail instead
of a dedicated VDDMEM rail as on STMP3780. Thus we are essentially running the
EMI at 130MHz at 1.050V when the minimum recommened voltage is 1.2V. This commit
runs the EMI at 64MHz all the time on the ZEN and ZEN X-Fi which will lead to
reduce performance but hopefully increases stability.
