Fat directory handling didn't check reaching the end of the root directory. It
relied on a stop condition based on a directory entry with a name starting with
a '\0' character. This check in itself is wrong ('\0' indicates free entry, not
end_of_directory) but outside the scope of this fix. For FAT32, the end of the
rootdir is reached when the end of the cluster chain is reached. The code didn't
check this condition and started to read an incorrect cluster. This caused a
subsequent read request of a sector outside the range of the usb stick in
use. On its turn, the usb stick protested with a stall handshake.

Both FAT32 and non-FAT32 (FAT16/FAT12) end or rootdir checks have been put in.

The reset request in usb_stor_get_info is causing issues with some usb
sticks. Some of these sticks vendor_id/product_id have been hardcoded to
not reset but better is to remove the reset altogether. It is not needed.

If NCE is hooked up to NCS3, we don't need to (and can't)
explicitly set the state of the NCE pin. Instead, the
controller asserts it automatically as part of a
command/data access. Only "CE don't care"-type NAND chips
can be used in this manner.

This patch adds support for reading an ONFI page parameter from a NAND
device supporting it. If this is the case, struct nand_chip onfi_version
member contains the supported ONFI version, 0 otherwise.

This allows NAND drivers past nand_scan_ident to set the best timings for the
NAND chip.

Commit 44c6e659 "rename _end to __bss_end__ broke building of a large
number of systems (at least all PowerPC?):

libstubs.o: In function `app_startup':
examples/standalone/stubs.c:197: undefined reference to `__bss_end__'

The rename should not be done for the files in the
examples/standalone/ directory, as these are not using the code from
start.S, but do their own BSS clearing, and either use their own
linker scripts or the ones provided by the compilers.

The function find_sector() does not take into account if the flash bank
has changed since the last call. This could lead to illegal accesses inside
and beyond the flash_info_t info strcture. For example if the current
flash bank has less sectors than the last used flash bank.

This patch adds two cheks. One that insures, that the current sector does
not exceed the allowed maximum (which is always a good idea). And one that
checks if the current access is to the same flash bank as the last access.
If not, the search loop will start with sector 0.
