A FAT12/FAT16 root directory location is specified by a sector offset and
it might not start at a cluster boundary. It also resides before the
data area (before cluster 2).
However, the current code assumes that the root directory is located at
a beginning of a cluster, causing no files to be found if that is not
the case.
Since the FAT12/FAT16 root directory is located before the data area
and is not aligned to clusters, using unsigned cluster numbers to refer
to the root directory does not work well (the "cluster number" may be
negative, and even allowing it be signed would not make it properly
aligned).
Modify the code to not use the normal cluster numbering when referring to
the root directory of FAT12/FAT16 and instead use a cluster-sized
offsets counted from the root directory start sector.
This is a relatively common case as at least the filesystem formatter on
Win7 seems to create such filesystems by default on 2GB USB sticks when
"FAT" is selected (cluster size 64 sectors, rootdir size 32 sectors,
rootdir starts at half a cluster before cluster 2).
dosfstools mkfs.vfat does not seem to create affected filesystems.

fs: ext4: Problem with ext4load and sparse files
Hi,
when I try to load a sparse file via ext4load, I am getting the error message
'invalid extent'
After a deeper look in the code, it seems to be an issue in the function ext4fs_get_extent_block in fs/ext4/ext4_common.c:
The file starts with 1k of zeros. The blocksize is 1024. So the first extend block contains the following information:
eh_entries: 1
eh_depth: 1
ei_block 1
When the upper layer (ext4fs_read_file) asks for fileblock 0, we are running in the 'invalid extent' error message.
For me it seems, that the code is not prepared for handling a sparse block at the beginning of the file. The following change, solved my problem:
I am really not an expert in ext4 filesystems. Can somebody please have a look at this issue and give me a feedback, if I am totally wrong or not?
Test cases are:
1) basic link creation, verify it can be followed
2) chained links, verify it can be followed
3) replace exiting file a with a link, and a link with a link. verify it
can be followed

now in milli-seconds instead of seconds with the new watchdog API.
Make sure to take this into account and only use a max timeout
value of 16 seconds as appropriate for this SoC.
Also the check against a lower timeout value than 0 is removed. This
check makes no sense, as the timeout value is unsigned.

watchdog: Handle SPL build with watchdog disabled
This patch adds some checks, so that the watchdog can be enabled in main
U-Boot proper but can be disabled in SPL.
This will be used by some AT91SAM based boards, which might enable the
watchdog in the main U-Boot proper and not in SPL. It will be enabled in
SPL by default there, so no need to configure it there. This approach
saves some space in SPL.

serial: atmel_usart: Use fixed clock value in SPL version with DM_SERIAL
This patch adds an alterative SPL version of atmel_serial_enable_clk().
This enables the usage of this driver without full clock support (in
drivers and DT nodes). This saves some space in the SPL image.
Please note that this fixed clock support is only added to the SPL code
in the DM_SERIAL part of this file. All boards not using SPL & DM_SERIAL
should not be affected.
This patch also introduces CONFIG_SPL_UART_CLOCK for the fixed UART
input clock. It defaults to 132096000 for ARCH_AT91 but can be set to
a different value if needed.

arm: at91: spl_at91.c: Call spl_early_init() if OF_CONTROL is enabled
This patch adds a call to spl_early_init() to board_init_f() which is
needed when CONFIG_SPL_OF_CONTROL is configured. This is necessary for
the early SPL setup including the DTB setup for later usage.
Please note that this call might also be needed for non SPL_OF_CONTROL
board, like the smartweb target. But smartweb fails to build with this
call because its binary grows too big. So I disabled it for these kind
of targets for now.

ARM: at91: sama5d2: Wrap cpu detection to fix macb driver
When introducing the SAMA5D27 SoCs, the SAMA5D2 series got an additional
chip id. The check if the cpu is sama5d2 was changed from a preprocessor
definition (inlining a call to 'get_chip_id()') to a C function,
probably to not call get_chip_id twice?
That however broke a check in the macb ethernet driver. That driver is
more generic and also used for other platforms. I suppose this solution
was implemented to use it in 'gem_is_gigabit_capable()', without having
to stricly depend on the at91 platform:
That only works as long as cpu_is_sama5d2 is a preprocessor definition.
(The same is still true for sama5d4 by the way.) So this is a straight
forward fix for the workaround.
The not working check on the SAMA5D2 CPU lead to an issue on a custom
board with a LAN8720A ethernet phy connected to the SoC:
