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.

Onda VX747 sim was missing a limits #define; #include limits.h in
pcm_sw_volume.h.
Simply use the software volume control for the SIM volume control
rather than the SDL volume control when the target would have it
natively.

Implements double-buffered volume, balance and prescaling control in
the main PCM driver when HAVE_SW_VOLUME_CONTROL is defined ensuring
that all PCM is volume controlled and level changes are low in latency.
Supports -73 to +6 dB using a 15-bit factor so that no large-integer
math is needed.
Low-level hardware drivers do not have to implement it themselves but
parameters can be changed (currently defined in pcm-internal.h) to work
best with a particular SoC or to provide different volume ranges.
Volume and prescale calls should be made in the codec driver. It should
appear as a normal hardware interface. PCM volume calls expect .1 dB
units.

Not moving fixedpoint.c for now since I'm not sure where it

In the modern everything-can-be-skinned world, themes are beginning
to hit the limit of 8 fonts (which includes sysfont). Increasing this
to 12 will allow some headroom, at the cost of a bit more RAM usage
(about 20 bytes per extra possible font, so about 80 bytes total here)

The old way actually mis-used the API (I misunderstood the docs) because
it specified the marker position as a "low buffer watermark" but instead of a
future playback head position.
The replacement is a simple thread that writes the data regardless of the
filling level of the buffer (write() will just block) and polls the playback
state periodically.

This was spotted while playing with qemu-jz:
1) rockbox reads TECR and TESR which are described as write-only
registers. Datasheet doesn't mention what happens if they are
readed. Apparently this doesn't have fatal side effects.
It comes down to two defines from jz4740.h
__tcu_stop_counter(n) and __tcu_start_counter(n) which use
read-modify-write sequence.
2) rockbox accesses out of bound offset 0xd4 in DMA memspace.
It comes from dis_irq() in system-jz4740.c. NUM_DMA is 6 but
DMA channels are 0-5 so (irq <= IRQ_DMA_0 + NUM_DMA)) bound
check is wrong.
This are *NOT* tested on device.

This patch adds to YP-R0 (and other future targets using Linux
framebuffer) the ability to use LCD_ENABLE to save some CPU cycles
while display is powered off.
This patch also changes the way to toggle LCD power: now using
a proper ioctl call, slightly more efficient.

commit_discard_dcache_range() is used in sd, lcd and pcm drivers
to handle transfers form/to data buffers so this should not introduce
any problems. It is reported to fix pop noise observed on some hifimans.

The build of bootloader with HAVE_ATA_DMA fails because of missing
commit_discard_dcache(). This seems to be bigger problem as
bootloader builds don't call cache_init() also which seems wrong.
but I know too little about the PP platform to judge.
For now use ATA DMA only in regular builds.

PP502x ATA DMA was disabled in 55fab77 because it caused various
instability on all targets using it. This instability is fixed in
583c948 via FS#12391. Here, ATA DMA is enabled for all PP502x targets
except nano1g and hdd6330. For nano1g, there may be other causes of
instability and more testing is needed. ATA DMA does not work on hdd6330.

In commit_discard_idcache(), cache lines were marked as invalid. When
some cache lines are marked as invalid, memory corruption can occur.
This caused instability when using PP502x ATA DMA because of the many
more calls to that function. Here, commit_discard_idcache() is changed
to avoid the problem. Also, the cache is filled after being enabled to
to ensure there are never any cache lines that aren't marked as valid.

The SD driver doesn't initialised drives at the beginning but

Move to a table based approach (scales better) and distinguish
between upward changes (increase frequency) and downward changes
(decrease frequency). This provides a better ordering of
operations and in particular it allows to avoid changing the
regulator while running at low speed since it takes a long time !
This should result in a much smoother scaling.
