eef21cb18a Change alignment macros to allow further performance optimization. Define the CACHEALIGN macros for all ARM CPUs, the used alignment size is derived from CACHEALIGN_BITS which has been defined for each supported ARM CPU with r28619. The default alignment size for ARM is set to 32 bytes as new -- not yet supported -- ARM CPUs will most probably need this alignment. To be able to differ between ARM and other CPUs a new macro called MEM_ALIGN_ATTR is introduced. This equals CACHEALIGN_ATTR for ARM, 16 byte alignment for Coldfire and is kept empty for other CPUs. MEM_ALIGN_ATTR is available system wide. From measurements it is expected that the usage of MEM_ALIGN_ATTR can give significant performance gain on ARM11 CPUs.

dd5dd8cfd9 Rename cache coherency functions. 
The old cache coherency function names where wrong and misleading.
The new names are (purposely different from vendor manuals)
*  commit_* (write-back only)
*  discard_* (removing lines from cache only)
*  commit_discard_* (write-back and removing lines from cache)

It's suspected the old names have led to wrong uses. The old names still exist
(as aliases) so every call via the old names need to be double checked and changed
to the new name.

a72aa856bd Move some gcc extensions to new gcc_extensions.h header 
- Move ATTRIBUTE_PRINTF/ATTRIBUTE_SCANF from _ansi.h
  They are not related at all to this file, and this broke compilation
  with Code Sourcery GCC which ships its own _ansi.h
- Move LIKELY/UNLIKELY from system.h

There is likely a lot more GCC extensions used everywhere in the source,
conditionally on __GNUC__ or unconditionally

e286b0bbc0 Remove atomic register bit manipulation functions from i.MX and s3c target code and introduce generic functions for ARM (bitmod32, bitset32, and bitclr32). Multiprocessor support is possible but just not implemented at the moment, only interrupt lockout.

2494afccc4 playback.c: don't assume cacheline size is 16 bytes 
ideally all targets should define CACHEALIGN_BITS, for now we default it
to 16 bytes if it's not specified

Since the buffer is already aligned in playback.c no need to align it
again in buffering.c

35e8b1429a Rockbox as an application: Replace many occurences of #ifdef SIMULATOR with #if (CONFIG_PLATFORM & PLATFORM_HOSTED) (or equivalently). 
The simulator defines PLATFORM_HOSTED, as RaaA will do (RaaA will not define SIMULATOR).
The new define is to (de-)select code to compile on hosted platforms generally.

Should be no functional change to targets or the simulator.

3d0cee8abb - Move uisimulator/sdl/*.[ch] into the target tree, under firmware/target/hosted/sdl, uisdl.c is split up across button-sdl.c and system-sdl.c. 
- Refactor the program startup. main() is now in main.c like on target, and the implicit application thread will now act as our main thread (previously a separate one was created for this in thread initialization).

This is part of Rockbox as an application and is the first step to make an application port from the uisimulator. In a further step the sim bits from the sdl build will be separated out.

27cf677339 Add a complete priority inheritance implementation to the scheduler (all mutex ownership and queue_send calls are inheritable). Priorities are differential so that dispatch depends on the runnable range of priorities. Codec priority can therefore be raised in small steps (pcmbuf updated to enable). Simplify the kernel functions to ease implementation and use the same kernel.c for both sim and target (I'm tired of maintaining two ;_). 1) Not sure if a minor audio break at first buffering issue will exist on large-sector disks (the main mutex speed issue was genuinely resolved earlier). At this point it's best dealt with at the buffering level. It seems a larger filechunk could be used again. 2) Perhaps 64-bit sims will have some minor issues (finicky) but a backroll of the code of concern there is a 5-minute job. All kernel objects become incompatible so a full rebuild and update is needed.

Recommended GOP size is about 15-30 frames depending on target or seeking can be slow with really long GOPs (nature of MPEG video).

57d71e4267 Add some CACHEALIGN_* macros and a helper function to assist in aligning data and buffers on PortalPlayer processors to cache line boundaries. They're noops when PROC_NEED_CACHEALIGN isn't defined. Go safe and increase the value to 32 since I'm not sure yet if 16 is sufficient - changing that is a one-liner. Add helper to plugin API which will be needed shortly.

a9b2fb5ee3 Finally full multicore support for PortalPlayer 502x targets with an eye towards the possibility of other types. All SVN targets the low-lag code to speed up blocking operations. Most files are modified here simple due to a name change to actually support a real event object and a param change to create_thread. Add some use of new features but just sit on things for a bit and leave full integration for later. Work will continue on to address size on sensitive targets and simplify things if possible. Any PP target having problems with SWP can easily be changed to sw corelocks with one #define change in config.h though only PP5020 has shown an issue and seems to work without any difficulties.

bfb281ff63 Messages queues must be guarded on both ends or else it's a race between detecting a message present and missing a wakeup on thread about to wait. Keeping IRQs from interacting with the scheduler would be preferable but this should do at the moment. Add more detailed panic info regarding blocking violations so we know who. Make panicf function well enough on Gigabeat and PortalPlayer targets. Move the core sleep instructions into a CPU-specific inline to keep thing organized.

d95c39072a Portal Player: Add invalidate_icache and flush_icache. Flush the cache on the core for newborn threads. In doing so, move more ARM stuff to the target tree and organize it to make a clean job of it. If anything isn't appropriate for some particular device give a hollar or even just fix it by some added #ifdefing. I was informed that the PP targets are register compatible so I'm going off that advice. The Sansa likes it though.
