This patch dramatically drops the amount of time u-boot needs to read a
file from an ext2 partition. On a typical 2 to 5 MB file (kernels and
initrds) it goes from tens of seconds to a couple seconds.
All we are doing here is grouping contiguous blocks into one read.
Boot tested on Globalscale Technologies Dreamplug (Kirkwood ARM SoC)
with three different files. sha1sums were calculated in Linux
userspace, and then confirmed after ext2load.

The FAT filesystem fails silently in inexplicable ways when given a
filesystem with a block-size that does not match the device sector size.
In theory this is not an unsupportable combination but requires a major
rewrite of a lot of the filesystem. Until that occurs, the filesystem
should detect that scenario and display a helpful error message.
This scenario in particular occurred on a 512-byte blocksize FAT fs
stored in an El-Torito boot volume on a CD-ROM (2048-byte sector size).
Additionally, in many circumstances the ->block_read method will not
return a negative number to indicate an error but instead return 0 to
indicate the number of blocks successfully read (IE: None).
The FAT filesystem should defensively check to ensure that it got all of
the sectors that it asked for when reading.
Signed-off-by: Kyle Moffett <Kyle.D.Moffett@boeing.com>
The FAT filesystem code currently ends up requiring that the partition
table be a DOS MBR, as it checks for the DOS 0x55 0xAA signature on the
partition table (which may be Mac, EFI, ISO9660, etc) before actually
computing the partition offset.
This fixes support for accessing a FAT filesystem in an ISO9660 boot
volume (El-Torito format) by reordering the filesystem checks and
reading the 0x55 0xAA "DOS boot signature" and FAT/FAT32 magic number
from the first sector of the partition instead of from sector 0.

Writing a file to the FAT partition didn't work while a
test using a CF card. The test was done on mpc5200 based
board (powerpc). There is a number of problems in FAT
write code:
Compiler warning:
fat_write.c: In function 'file_fat_write':
fat_write.c:326: warning: 'counter' may be used uninitialized
in this function
fat_write.c:326: note: 'counter' was declared here
'l_filename' string is not terminated, so a file name
with garbage at the end is used as a file name as shown
by debug code.
Return value of set_contents() is not checked properly
so actually a file won't be written at all (as checked
using 'fatls' after a write attempt with 'fatwrite'
command).
do_fat_write() doesn't return the number of written bytes
if no error happened. However the return value of this
function is used to show the number of written bytes
in do_fat_fswrite().
The patch adds some debug code and fixes above mentioned
problems and also fixes a typo in error output.
NOTE: after a successful write to the FAT partition (under
U-Boot) the partition was checked under Linux using fsck.
The partition needed fixing FATs:

In some cases, saving data in RAM as a file with FAT format is required.
This patch allows the file to be written in FAT formatted partition.
The usage is similar with reading a file.

in order to set target partition.
Then, file_fat_write function is invoked with desired file name,
start ram address for writing data, and file size.

Currently, if a device read request is done that does not begin or end
on a sector boundary a stack allocated bounce buffer is used to perform
the read, and then just the part of the sector that is needed is copied
into the users buffer. This stack allocation can mean that the bounce
buffer will not be aligned to the dcache line size. This is a problem
when caches are enabled because unaligned cache invalidates are not
safe.
This patch uses ALLOC_CACHE_ALIGN_BUFFER to create a stack allocated
cache line size aligned bounce buffer.

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.
