7fea136903 Autodetect sector size on superfloppy volumes based on the FAT32 BPB (kudos to Frank Gevaerts)

a8137252a5 FS#11118: reduce the number of cached sector in FAT code because some are useless after a rewrite of LFN entries handling. Also makes LFN handling more robust.

26c0e753d1 Rewrite dircache generation to take advantage for the FAT code. Reduce RAM usage by ~30Kb and binsize by at least several hundreds bytes. Also remove the directory depth limit of dircache.

14eb02d347 Patch #1 from FS#10633 (Nano 2G developments) by Michael Sparmann - Allows targets to set a different sector size than 512 for the storage system. Should not affect any other target.

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).

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).

0f03e3af31 Changed fat_getnext(): 
1) Fixed a bug where really long filenames could be messed up if they spanned 3 sectors
2) Now uses 2 buffers instead of 3, without copying the buffers with memcpy()
3) Can now use aligned sector reads, first step towards iPod 5.5G 80GB

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.

ae66c2b9ee Add support (runtime detection) for 2048 bytes/sector filesystem. 
Large sectors are enabled for iPod Video (including 5.5G) only. Might
still cause FS corruption (however, unlikely), so beware! Based on
FS#6169 by Robert Carboneau.
