42f77d4eb0 Abstract the PortalPlayer AS3514 handling with an "ascodec" API - inspired by the wmcodec API used with the Wolfson codecs. The intention is to implement this API for the AS3525 and then share code with the Sansa V2 ports.

2acc0ac542 Updated our source code header to explicitly mention that we are GPL v2 or 
later. We still need to hunt down snippets used that are not. 1324 modified

b4275d4941 Philips GoGear SA9200 port. Working bootloader and normal builds, including sound. No touchpad now, buttons limited to using vol+/vol-/power for up/down/select. Rockbox USB is enabled since the OF is MTP only...read the warnings on the PortalPlayerUsb wiki page.

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).

af395f4db6 Do core interrupt masking in a less general fashion and save some instructions to decrease size and speed things up a little bit. Small fix to a few places where interrupts would get enabled again where they shouldn't have been (context switching calls when disabled).

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.

06a5299aff Do some crackdown on kernel object reinitialization after they could be in use and use before initialization. For c200/e200: Be sure fat cache and ata locks are acquired in the proper order during hot swapping. Delay hotswap monitoring until after initial file mounting (address 2nd kobj concern + possible call of fat driver before init).

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.

dbc6b4e39a Sansa c200 port. Rockbox works with sound. Several features are disabled including some lcd options, FM radio, recording, and all plugins. Loading the OF from the Rockbox bootloader does not work.
