90ea991dff i.MX31: Issue some NOP's immediately after MCR WFI to prevent premature execution of subsequent code.

50a6ca39ad Move c/h files implementing/defining standard library stuff into a new libc directory, also standard'ify some parts of the code base (almost entirely #include fixes). 
This is to a) to cleanup firmware/common and firmware/include a bit, but also b) for Rockbox as an application which should use the host system's c library and headers, separating makes it easy to exclude our files from the build.

2f02d62234 Fix red from r25666 (forgot to use macro to not use core variable on single core), update a comment and remove core check for setting THREAD_SWITCH upon wakeup which is irrelevant to the idea behind the change.

d6cd1bc58e Threads of PRIORITY_REALTIME and above are no longer subject to being switched away based upon aging of lower priority threads. Now, recommend a thread switch in wakeup_thread of any thread of higher priority is ready to run.

376d8d577f Add IO priority handling. Currently all IO has equal priority, except the dircache scanning thread which is lower. This fixes the slow boot problem for me, with the added benefit that actual audio playback also starts faster. 
Lots of the changes are due to changing storage_(read|write)sectors() from macros to wrapper functions. This means that they have to be called with IF_MD2(drive,) again.

f8edc32589 FS#10756 - Free unused init code 
Introduce a new .init section for initialisation code, so that it can be copied to an area which is later overwritten before calling. The stack/bss can then overwrite that code, effectively freeing the code size that the initialisation routines need. Gives a few kB ram usage back.
Only implemented for PP and as3525 so far. More targets could be added, as well as more functions.

84f8b0be2c s3c2440 can use the generic ARM WFI which is much simpler. If there's any advantage to setting the IDLE bit for power consumption, it's possible to combine its use with the old core_sleep instead of using the loop waiting for idle to kick in. For now, go basic. Let GCC choose the register for MCR instead of forcing it to r0.

8cfbd3604f Use cookies for thread identification instead of pointers directly which gives a buffer against wrongly identifying a thread when the slot is recycled (which has been nagging me for awhile). A slot gets 255 uses before it repeats. Everything gets incompatible so a full update is required.

05099149f1 Enable nocache sections using the linker. PP5022/4 must use SW_CORELOCK now with shared variables in DRAM (it seems swp(b) is at least partially broken on all PP or I'm doing something very wrong here :\). For core-shared data use SHAREDBSS/DATA_ATTR. NOCACHEBSS/DATA_ATTR is available whether or not single core is forced for static peripheral-DMA buffer allocation without use of the UNCACHED_ADDR macro in code and is likely useful on a non-PP target with a data cache (although not actually enabled in config.h and the .lds's in this commit).

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.

32a531b09b Do some simplification in switch_thread regarding interrupt enabling which simplifies kernel objects as well. Simply doing unconditional disable/enable should be fine in the firmware.
