This work is based on:
- Fabien Sanglard's "Fabother World" based on
- Piotr Padkowski's newRaw interpreter which was based on
- Gregory Montoir's reverse engineering of
- Eric Chahi's assembly code
--------------------------------------------------------------------
Progress:
* The plugin runs pretty nicely (with sound!) on most color targets
* Keymaps for color LCD targets are complete
* The manual entry is finished
* Grayscale/monochrome support is NOT PLANNED
- the game looks horrible in grayscale! :p
--------------------------------------------------------------------
Notes:
* The original game strings were built-in to the executable, and
were copyrighted and could not be used.
* This port ships with an alternate set of strings by default, but
can load the "official" strings from a file at runtime.
--------------------------------------------------------------------
To be done (in descending order of importance):
* vertical stride compatibility <30% done>
* optimization <10% done>

The backlight driver always writes a bogus value
from memory into the LCD brightness register.
Fix it up by adding bounds checks and
use a more sane default value.
While looking at the code, I noticed
that BACKLIGHT_CONTROL_SET probably ignores
the desired brightness level, too.
Note: Please test on real hardware, I don't own it.

The refactoring of the audio thread in this commit
-----------------------------------------------
commit 5857c44017
Author: Michael Sevakis <jethead71@rockbox.org>

Refactor audio thread to run both recording and playback.
-----------------------------------------------
moved pcm_init() next to dsp_init() in apps/main.c:init().
Before that pcm_init() was called by audio_init().
Unfortunately the maemo init code didn't properly
wait until the maemo thread was fully initialized,
leading to dangling pointers when the code called
by pcm_init() tried to access maemo's variables.
Fix it by refactoring the "very fast shutdown" semaphore
to wait until maemo is initialized in any case.
This should also fix very rare rockbox crashes
on startup that I got once a year or so.
The new code has been tested by a script that
starts and kills rockbox after one second.

Turns out maemo's old gcc 4.2.1 doesn't include any arch
optimized swapXX() functions, just plain C implementations.
Before we pull in lots of linux kernel headers for the
C implementation, just stick to rockbox's own version.

Optimizes YUV to RGB conversion using ARMv5 multiply-accumulate
intructions for operations and data tables for saturation.
This first patch set includes the three versions i have developed.
Although iPod Classic need to use the latest version to reach 30fps,
old versions may serve other targets.
All versions are based on current SVN algorithm (round->scale->add)
using the same coefficients, so output results are identical.
Version history:
ARMv4:
- use all available registers to calculate four pixels within each
loop iteration.
- avoid LDR interlocks.
ARMv5TE:
- use ARMv5TE+ 1-cycle multiply-accumulate instructions.
ARMv5TE_WST:
- use data tables (256 bytes) for RBG565 saturation.
Benchmarks results using iPod Classic (ARM926EJ 216Mhz):
size test_fps (1) mpegplayer (2)
bytes YUV YUV1/4 average min/max
----- ----------- ------------------
SVN-20141107 528 27.8 110.0 11035 10864/13397
ARMv4 480 28.8 114.0 9767 9586/12126
ARMv5TE 468 29.7 117.5 8751 8584/11118
ARMv5TE_WST 544 33.6 133.0 6355 6316/6403
(1) boosted
(2) play full elephants_dream_320x240.mpg file (15693 frames) using
mpegplayer, patched RB measures YUV to RGB565 frame conversion
time (microseconds)
Compared against the WST version, the ARMV5TE version w/o cached
saturation tables is slower, but it is smaller and i have doubts
about the power consumption.

7d1a47cf13 introduced a regression that broke it completely so that
it couldn't boot into the main menu anymore. It had a faulty call to
get_volume_name() which made handle_special_links() act up. This broke
every open() and opendir() (and friends) library calls.

Commit 7d1a47cf ("Rewrite filesystem code (WIP)") exposed
bug in rk27xx sd driver. Buffer passed to sd_read/write_sectors()
doesn't has to be cacheline aligned. DMA transfers on
unaligned buffers is quiet dangerous thing.
Make sure that the buffer is aligned to cacheline size,
If not use a temporary aligned buffer for DMA transfer.

This file revealed several problems with our ASF parser:
1) The packet count in the ASF was actually a 64 bit value,
leading to overflow in very long files.
2) Seeking blindly trusted the bitrate listed in the ASF header
rather than computing it from the packet size and number of packets.
Fix these problems and fix a few minor issues.
