There is no reason not to use the Linux "jedec,spi-nor" binding in U-Boot
dts files. This compatible has been added in sf_probe, let use it.

This patch switches to jedec,spi-nor when spi-flash is used in the DTS
and DTSI files, and removed spi-flash when jedec,spi-nor is already
present.

The x86 dts are switched in a separate commit since it depends on a change
in fdtdec.

This patch sync's the U-Boot SPI NAND GigaDevice GD5F1GQ4UExxG support
with the latest Linux version (v5.0-rc3) plus the chip supported posted
on the MTD list. Only the currently in U-Boot available chip is
supported with this sync.

The changes for the GD5F1GQ4UExxG are:
- Name of NAND device changed to better reflect the real part
- OOB layout changed to only reserve 1 byte for BBT
- Use ECC caps 8bits/512bytes instead of 8bits/2048bytes
- Enhanced ecc_get_status() function to determine and report
  a more fine grained bit error status

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.

To help with this, introduce the assert_fs_integrity() function that

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.

v2018.01 commit e23eb942 ("ARM: rmobile: Stop using
rcar-common/common.c on Gen3") removed
board/renesas/rcar-common/common.c from the build chain with the
reasoning that calling arch_preboot_os() is no longer needed.

However, it left the arch_preboot_os() in place. Get rid of it.
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
other headers (common.h, rmobile.h) are going to be needed by pretty
much anything that is going to appear in the rcar common code. So, keep
the two in place.
