The present fat implementation ignores FAT16 long name
directory entries which aren't placed in a single sector.
This was becouse of the buffer was always filled by the
two sectors, and the loop was made also for two sectors.
If some file long name entries are stored in two sectors,
the we have two cases:
Case 1:
Both of sectors are in the buffer - all required data
for long file name is in the buffer.
- Read OK!
Case 2:
The current directory entry is placed at the end of the
second buffered sector. And the next entries are placed
in a sector which is not buffered yet. Then two next
sectors are buffered and the mentioned entry is ignored.
- Read fail!
This commit fixes this issue by:
- read two sectors after loop on each single is done
- keep the last used sector as a first in the buffer
before the read of two next
The commit doesn't affects the fat32 imlementation,
which works good as previous.

The sandbox/ext4/fat/generic fs commands do not gracefully deal with files
greater than 2GB. Negative values are returned in such cases.
To handle this, the fs functions have been modified to take an additional

of the fs functions are used only for error conditions.

ext4fs_allocate_blocks() always allocates at least one block for a file.
If the file size is zero, this causes total_remaining_blocks to

When write a file into FAT file system, it will search a match file in
root dir. So the find_directory_entry() will get the first cluster of
root dir content and search the directory item one by one. If the file
is not found, we will call get_fatent_value() to get next cluster of root
dir via lookup the FAT table and continue the search.
The issue is in FAT16/12 system, we cannot get root dir's next clust
from FAT table. The FAT table only be use to find the clust of data
aera in FAT16/12.
In FAT16/12 if the clust is in root dir, the clust number is a negative
number or 0, 1. Since root dir is located in front of the data area.
Data area start clust #2. So the root dir clust number should < 2.
This patch will check above situation before call get_fatenv_value().
If curclust is < 2, include minus number, we just increase one on the
curclust since root dir is in continous cluster.
The patch also add a sanity check for entry in get_fatenv_value().

In fat_write.c, the last clust condition check is incorrect:

}
For example, in FAT32 if curclust is 0x11000. It is a valid clust.
But on above condition check, it will be think as a last clust.
So the correct last clust check should be:
in fat32, curclust >= 0xffffff8
in fat16, curclust >= 0xfff8
in fat12, curclust >= 0xff8
This patch correct the last clust check.

This bug shows up when file stored on the ext4 file system is updated.
The ext4fs_delete_file() is responsible for deleting file's (e.g. uImage)
data.
However some global data (especially ext4fs_indir2_block), which is used
during file deletion are left unchanged.
The ext4fs_indir2_block pointer stores reference to old ext4 double
indirect allocated blocks. When it is unchanged, after file deletion,
ext4fs_write_file() uses the same pointer (since it is already initialized
- i.e. not NULL) to return number of blocks to write. This trunks larger
file when previous one was smaller.
Lets consider following scenario:
1. Flash target with ext4 formatted boot.img (which has uImage [*] on itself)
2. Developer wants to upload their custom uImage [**]
- When new uImage [**] is smaller than the [*] - everything works
correctly - we are able to store the whole smaller file with corrupted
ext4fs_indir2_block pointer
- When new uImage [**] is larger than the [*] - theCRC is corrupted,
since truncation on data stored at eMMC was done.
3. When uImage CRC error appears, then reboot and LTHOR/DFU reflashing causes
proper setting of ext4fs_indir2_block() and after that uImage[**]
is successfully stored (correct uImage [*] metadata is stored at an
eMMC on the first flashing).
Due to above the bug was very difficult to reproduce.
This patch sets default values for all ext4fs_indir* pointers/variables.

In an ext4 filesystem, the inode corresponding to a file has a 60-byte
area which contains an extent header structure and up to 4 extent
structures (5 x 12 bytes).
For files that need more than 4 extents to be represented (either files
larger than 4 x 128MB = 512MB or smaller files but very fragmented),
ext4 creates extent index structures. Each extent index points to a 4KB
physical block where one extent header and additional 340 extents could
be stored.
The current u-boot ext4 code is very inefficient when it tries to load a
file which has extent indexes. For each logical file block the code will
read over and over again the same blocks of 4096 bytes from the disk.
Since the extent tree in a file is always the same, we can cache the
extent structures in memory before actually starting to read the file.
This patch creates a simple linked list of structures holding information
about all the extents used to represent a file. The list is sorted by
the logical block number (ee_block) so that we can easily find the
proper extent information for any file block.
Without this patch, a 69MB file which had just one extent index pointing
to a block with another 6 extents was read in approximately 3 minutes.
With this patch applied the same file can be read in almost 20 seconds.

This commit changes the working directory
where the build process occurs.
Before this commit, build process occurred under the source
tree for both in-tree and out-of-tree build.
That's why we needed to add $(obj) prefix to all generated
files in makefiles like follows:
$(obj)u-boot.bin: $(obj)u-boot
Here, $(obj) is empty for in-tree build, whereas it points
to the output directory for out-of-tree build.
And our old build system changes the current working directory
with "make -C <sub-dir>" syntax when descending into the
sub-directories.
On the other hand, Kbuild uses a different idea
to handle out-of-tree build and directory descending.
The build process of Kbuild always occurs under the output tree.
When "O=dir/to/store/output/files" is given, the build system
changes the current working directory to that directory and
restarts the make.
Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>"
syntax for descending into sub-directories.
(We can write it like "make $(obj)=<sub-dir>" with a shorthand.)
This means the current working directory is always the top
of the output directory.

As documented, almost all U-Boot commands expect numbers to be entered
in hexadecimal input format. (Exception: for historical reasons, the
"sleep" command takes its argument in decimal input format.)
This rule was broken for the "load" command; for details please see
especially commits 045fa1e "fs: add filesystem switch libary,
implement ls and fsload commands" and 3f83c87 "fs: fix number base
behaviour change in fatload/ext*load". In the result, the load
command would always require an explicit "0x" prefix for regular
(i. e. base 16 formatted) input.
Change this to use the standard notation of base 16 input format.
While strictly speaking this is a change of the user interface, we
hope that it will not cause trouble. Stephen Warren comments (see
[1]):
I suppose you can change the behaviour if you want; anyone
writing "0x..." for their values presumably won't be
affected, and if people really do assume all values in U-Boot
are in hex, presumably nobody currently relies upon using
non-prefixed values with the generic load command, since it
doesn't work like that right now.

In the set_cluster() function, it will convert the buffer size to sector
numbers. Then call disk_write() to write by sector.
For remaining buffer, the size is less than a sector, call disk_write()
again to write them in one sector.
But if the total buffer size is less then one sector, the original code
will call disk_write() with zero sector number. It is unnecessary.
So this patch fix this. Now it will not call disk_write() if total buffer size
is less than one sector.

With CONFIG_SYS_64BIT_LBA, lbaint_t gets defined as a 64-bit type,
which is required to represent block numbers for storage devices that
exceed 2TiB (the block size usually is 512B), e.g. recent hard drives
We now use lbaint_t for partition offset to reflect the lbaint_t change,
and access partitions beyond or crossing the 2.1TiB limit.
This required changes to signature of ext4fs_devread(), and type of all
variables relatives to block sector.
ext2/ext4 fs uses logical block represented by a 32 bit value. Logical
block is a multiple of device block sector. To avoid overflow problem
when calling ext4fs_devread(), we need to cast the sector parameter.

This patch is essentially an update of u-boot MTD subsystem to
the state of Linux-3.7.1 with exclusion of some bits:
- the update is concentrated on NAND, no onenand or CFI/NOR/SPI
flashes interfaces are updated EXCEPT for API changes.
- new large NAND chips support is there, though some updates
have got in Linux-3.8.-rc1, (which will follow on top of this patch).
To produce this update I used tag v3.7.1 of linux-stable repository.
The update was made using application of relevant patches,
with changes relevant to U-Boot-only stuff sticked together
to keep bisectability. Then all changes were grouped together
to this patch.

This allows write of files from the host filesystem in sandbox. There is
currently no concept of overwriting the file and removing its existing
contents - all writing is done on top of what is there. This means that
writing 10 bytes to the start of a 1KB file will only update those 10
bytes, not truncate the file to 10 byte slong.
If the file does not exist it is created.

UBI can mount volumes by name or number The current code forces you
to name the volume by prepending every name with "ubi:".
>From fs/ubifs/super.c
* There are several ways to specify UBI volumes when mounting UBIFS:
* o ubiX_Y - UBI device number X, volume Y;
* o ubiY - UBI device number 0, volume Y;
* o ubiX:NAME - mount UBI device X, volume with name NAME;
* o ubi:NAME - mount UBI device 0, volume with name NAME.
Now any name passed in any of the above forms are allowed.

In case a function argument is known/fixed size array in C, the argument is
still decoyed as pointer instead ( T f(U n[k]) ~= T fn(U *n) ) and therefore
calling sizeof on the function argument will result in the size of the pointer,
not the size of the array.

The ext4write code has been using direct calls to 64-32 division
(/ and %).
Officially supported u-boot toolchains (eldk-5.[12].x) generate calls
to __aeabi_uldivmod(), which is niether defined in the toolchain libs
nor u-boot source tree.
Due to that, when the ext4write command has been executed, "undefined
instruction" execption was generated (since the __aeabi_uldivmod()
is not provided).
To fix this error, lldiv() for division and do_div() for modulo have
been used.
Those two functions are recommended for performing 64-32 bit number
division in u-boot.

u-boot's byteorder headers did not contain endianness attributions
for use with sparse, causing a lot of false positives. Import the
kernel's latest definitions, and enable them by including compiler.h
and types.h. They come with 'const' added for some swab functions, so
fix those up, too:
include/linux/byteorder/big_endian.h:46:2: warning: passing argument 1 of '__swab64p' discards 'const' qualifier from pointer target type [enabled by default]
Also, note: u-boot's historic __BYTE_ORDER definition has been
preserved (for the time being at least).
We also remove ad-hoc barrier() definitions, since we're including
compiler.h in files that hadn't in the past:
macb.c:54:0: warning: "barrier" redefined [enabled by default]
In addition, including compiler.h in byteorder changes the 'noinline'
definition to expand to __attribute__((noinline)). This fixes
arch/powerpc/lib/bootm.c:
bootm.c:329:16: error: attribute '__attribute__': unknown attribute
bootm.c:329:16: error: expected ')' before '__attribute__'
