646edc594f Fix bpb_is_sane() cluster size calculation for non-512 byte sectors. 
bpb_is_sane() used to effectively multiplying the sector size (relative
to 512 bytes) twice, which meant that filesystems with e.g. 2K sectors and
32 sectors per cluster were rejected because while this adds up to 64K
clusters (i.e. the upper limit), the calculation wrongly came to 256K.

This bug tends to affect 5.5G ipods when formatted using dosfstools.

a56f1ca1ed Cleanup MV/MD macros a little. 
When using variadic macros there's no need for IF_MD2/IF_MV2 to deal
with function parameters. IF_MD/IF_MV are enough.

Throw in IF_MD_DRV/ID_MV_VOL that return the parameter if MD/MV, or 0
if not.

18c016b4e0 Fix test fat failing on 64bit system (second bit of FS#12646) 
We use unsigned long/long in number of places in fat.c. When this
is used to cast 32bit fat field it fails on 64bit systems.
This patch introduces explicit types (uint16_t, uint32_t) only
in places which influence how fat structures are interpreted.

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.

bf9facc49c FAT timestamp handling improvements for non-RTC targets: 
- When writing to a file that is older than the build, file date is set to the build date.
- Time is advanced so that the minutes are a multiple of 11, excluding '00', and seconds = 
  minutes. This is done as a hint that the time isn't 100% correct.
- Date increment uses actual month lengths (but without leap year handling)

2f8a0081c6 Apply FS#9500. This adds a storage_*() abstraction to replace ata_*(). To do that, it also introduces sd_*, nand_*, and mmc_*. 
This should be a good first step to allow multi-driver targets, like the Elio (ATA/SD), or the D2 (NAND/SD).

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.

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.

ef3e129b65 Much simpler implementation of large virtual sector support, not needing larger sector buffers and not touching file.c at all. secmult is simply used to normalize all sector counts to 512-byte physical sectors. * Moved MAX_SECTOR_SIZE definition to config-*.h, and enabled it for iPod Video only. MAX_SECTOR_SIZE now only enables checking for alternate disk layouts due to sector size (as iPod Video G5.5 is presented as having 2048-byte _physical_ sectors to the PC). Large virtual sector support in fat.c is always enabled.
