Under some circumstance (timeout), the dma interrupt is not fired
and only the error one is. This can happen with some picky SD
cards and with the current code it causes a 1 second timeout.
This code properly catches the error interrupt to stop as soon
as possible.

The current pwm interface is too low-level. Introduce a higher
level setup function which directly computes the parameters from
the required frequency.

The clkctrl functions were becoming a mess. Normalise the names,
get rid of the xtal derived as special case and use the same
interface.

A number of pins on the imx233 are standard and manually calling
functions to acquire, set function/drive/output is painful. This
will become unmanageable when we will add support for the other
stmp chips.
Introduce the concept of virtual pin which is a way to completely
describe a virtual pin (virtual because pins are muxed).

The current pinctrl functions were a mess. Normalise the functions
names to make them shorter and clearer.

The SD SWITCH command has a result and can take a long time to
finish. Ignoring the answer and waiting an arbitrary time is
unreliable at best.

Register set selection is based on the value of the
IMX233_SUBTARGET value. The reg-select.h file (used by the
generated headers), does the selection based on this value as
follows:
- 3600 <= . < 3700: stmp3600 register set
- 3700 <= . < 3780: stmp3700 register set
- 3780 <= .: imx233 register set
Note that this selector relies on the name of the socs in the
register description to be respectively stmp3600, stmp3700 and
imx233.

This causes data_abort_handler from lib/unwarminder/safe_read.S to be
used instead. It allows unwarminder to avoid data aborts when
displaying the backtrace. A data_abort_handler remains in system-arm.c,
but it is not used because it is declared as a weak symbol.

Split the ISR into two parts and alllow quick return from first half.
Introduces a uevent() API to have a callback happen in a specified
number of microseconds. Right now only one event is supported.

This speeds up partial updates quite a bit but what is more
important it opens up a way to efficiently implement
lcd_blit_yuv() using hw colorspace conversion.
Tested on rk27generic, hm60x v1 and v2 and on ma9.
Benchmark for hm60x v1 (by mortalis):
HEAD patched
1/1 141fps 138fps

Based on FS#9920 by Ryan Press with changes to selection logic so
that it works on my iPod Photo. Should also work on iPod Color/4G
and Mini2G. Moved all target specific code from
firmware/drivers/serial.c into new file
firmware/target/arm/pp/uart-pp.c in the same manner as other
target specific uart code.
Update to fix build error on ipodmini2g by adding defines in config file.
Removed unwanted whitespace
Tested on iPod Photo.

This is going right in since it's long overdue. If anything is goofed,
drop me a line or just tweak it yourself if you know what's wrong. :-)
Make HW/SW codec interface more uniform when emulating HW functionality
on SWCODEC for functions such as "audiohw_set_pitch". The firmware-to-
DSP plumbing is in firmware/drivers/audiohw-swcodec.c. "sound_XXX"
APIs are all in sound.c with none in DSP code any longer.
Reduce number of settings definitions needed by each codec by providing
defaults for common ones like balance, channels and SW tone controls.
Remove need for separate SIM code and tables and add virtual codec header
for hosted targets.
