fs: fat: fix reading non-cluster-aligned root directory

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).

Hi,

when I try to load a sparse file via ext4load, I am getting the error message

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: fs: Add filesystem integrity checks

We need to make sure that file writes,file creation, etc. are properly
performed and do not corrupt the filesystem.
To help with this, introduce the assert_fs_integrity() function that

fs: ext4: cache extent data

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

extents. Implement a very dumb cache to prevent repeatedly reading the

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:

#ifndef cpu_is_sama5d2
#define cpu_is_sama5d2() 0
#endif

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:

=> dhcp
ethernet@f8008000: PHY present at 1
ethernet@f8008000: Starting autonegotiation...

Retry time exceeded; starting again

Notice the wrong reported link speed, although both SoC and phy only
support 100 MBit/s!

The real issue on reliably detecting the features of that cadence
ethernet mac IP block, is probably more complicated, though.

arm: sunxi: Enable DM_MMC on required SoCs

Enabling DM_MMC is forcing CONFIG_BLK=y so if any board which uses
SCSI must need to enable DM_SCSI otherwise SCSI reads on that particular
target making invalid reading to the disk drive.

Allwinner platform do support SCSI on A10, A20 and R40 SoC's out of
these only A10 have DM_SCSI enabled. So enabling DM_MMC on A20, R40
would eventually end-up with scsi disk read failures like [1]

So, enable DM_MMC in all places of respective SoC's instead of enabling
them globally to Allwinner platform.

Now, DM_MMC is enabled in Allwinner SoC's except A20 and R40.

efi_loader: EFI_PRINT instead of debug for variable services

macro which gives us well aligned output like:

EFI: Entry efi_get_variable("PlatformLang" ...)
  EFI: get 'efi_8be4df61-93ca-11d2-aa0d-00e098032b8c_PlatformLang'

5 years agoefi_loader: set image_base and image_size to correct values

efi_loader: set image_base and image_size to correct values

Currently, image's image_base points to an address where the image was
temporarily uploaded for further loading. Since efi_loader relocates
the image to final destination, image_base and image_size should reflect
that.

This bug was detected in UEFI SCT, "Loaded Image Protocol Test - test 2,"
which shows that 'Unload' function doesn't fit into a range suggested by
image_base and image_size.

LoadedImageBBTestMain.c:1002

Changes in this patch also includes:
* reverts a patch, "efi_loader: save image relocation address
  and size" since newly added fields are no longer needed.
* copy PE headers as well since those information will be needed
  for module loading, in particular, at gurb.
