The 'u-boot,i2c-transaction-bytes' device tree property provides
information regarding number of bytes transferred by a device in a
single transaction.
This change is necessary to avoid hanging devices after soft reset.
One notable example is communication with MC34708 device:
1. Reset when communicating with MC34708 via I2C.
2. The u-boot (after reboot -f) tries to setup the I2C and then calls
force_idle_bus. In the same time MC34708 still has some data to be sent
(as it transfers data in 24 bits chunks).
3. The force_idle_bus() is not able to make the bus idle as 8 SCL
clocks may be not enough to have the full transmission.
4. We end up with I2C inconsistency with MC34708.
This PMIC device requires 24+ SCL cycles to make finish any pending I2C
transmission.

On modern Allwinner SoCs (tested: H2+, A64, H5, H6) the BootROM can
actually load the SPL also from sector 256 (128KB) of an SD card or eMMC
chip. For more details, see [1].
In this case the boot source indicator (written at offset 0x28 of SRAM A1)
has bit 4 set, so it's 0x10 for SD card and 0x12 for eMMC.
Add those new values to the existing boot source check to allow booting
the SPL from those "high" disk offsets as well. For this to work, the
value of CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR needs to be adjusted,
for instance to 0x140 (right after the high SPL). Doing this dynamically
sounds desirable, but looks nasty to implement.

While the exact problem is not known, based on discussion between
Philipp Tomsich and André Przywara it is guessed that exit self-refresh
timing is not set with correct value. There may be implicit enter or
exit Self-Refresh anywhere as part of some training phase.
In ZynqMP register guide [1], which is close to the various
Allwinner DRAM controllers, tXSDLL is bits [14:8], while the non-DLL
tXS is bits [6:0]: Self refresh exit delay. So it could be safely
increased and it only affects the time after the self-refresh “exit”,
which happens only after (re-)initialisation.
There was no document for cpu in question so based on oscilloscope
readings [2][3] and observed result by comparing allwinner architecture.
So set it same as Allwinner H5 silicon.
Before this patch, failure rate of was 7%.
This was tested on A33 allwinner cpu, dual rank connection connected
with two MT41K512M16HA-125:A memory model. Memory is configured as DDR3
1.5V
And also this is tested in A33-OLinuXino dev board.

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.

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
4) create a broken link, verify it can't be followed

Re-use the functions used to write/create a file, to support creation of a
symbolic link.
The difference with a regular file are small:
- The inode mode is flagged with S_IFLNK instead of S_IFREG
- The ext2_dirent's filetype is FILETYPE_SYMLINK instead of FILETYPE_REG
- Instead of storing the content of a file in allocated blocks, the path
to the target is stored. And if the target's path is short enough, no block
is allocated and the target's path is stored in ext2_inode.b.symlink
As with regulars files, if a file/symlink with the same name exits, it is
unlinked first and then re-created.

When a file contains extents, U-Boot currently reads extent-related data
for each block in the file, even if that data is located in the same
block each time. This significantly slows down loading of files that use
extents. Implement a very dumb cache to prevent repeatedly reading the
same block. Files with extents now load as fast as files without.
Note: There are many cases where read_allocated_block() is called. This
patch only addresses one of those places; all others still read redundant
data in any case they did before. This is a minimal patch to fix the
load command; other cases aren't fixed.

This is done in preparation of resurrecting rcar-common/common.c.
NOTE: The three removed header includes (io.h, sys_proto.h, rcar-mstp.h)
are in direct relationship with the dropped arch_preboot_os() hook. The
