fix the warning with gcc 4.2, as found in ELDK 4.2.

ext2load: increase read speed

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.

fs/fat: Improve error handling

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.

fs/fat: Fix FAT detection to support non-DOS partition tables

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.

FAT: fix some issues in FAT write support code

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:
-bash-3.2# fsck -a /dev/sda1
fsck 1.39 (29-May-2006)
dosfsck 2.11, 12 Mar 2005, FAT32, LFN
FATs differ but appear to be intact. Using first FAT.
