At least one person found an SD card that wouldn't work at 2.7v.

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.

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 ;)

As preparation to add new targets to the s5l8702 directory,
rename files as:

s5l8702/ipod6g/*-ipod6g.c -> s5l8702/ipod6g/*-6g.c

* 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* Text is no longer updated until a complete group has been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).
