2016-09-26i2c: mvtwsi.c: Add support for Marvell Armada 7K/8KStefan Roese
By adding the "marvell,mv78230-i2c" compatible property, we can enable this I2C driver to support these new ARM64 chips as well.

2016-09-26i2c: mv_i2c.c: Validate read length in I2C commandjinghua
The I2C bus will get stuck when reading 0 byte. So we add validation of the read length in i2c_read(). This issue only occurs on read operation.

This board is a plug in card for Marvell's switch system development kits.

88F6820 is a specific Armada-38x chip that is used on the DB-88F6820-GP board. Rather than having DB_88F6820_GP and TARGET_DB_88F6820_GP which selects the former.

2016-09-24usb: ehci-generic: support reset control for generic EHCIMasahiro Yamada
This driver is designed in a generic manner, so resets should be handled generically as well. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2016-09-24reset: add no-op stubs for optional reset controlMasahiro Yamada
My motivation for this patch is to make reset control handling optional for generic drivers. I want to add reset control to drivers/usb/host/ehci-generic.c, but it is used by several platforms, some will implement a reset controller driver, some will not. Add no-op stubs in order to avoid link error for drivers that implement reset controlling, but still it is optional. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

Replace all include directives for <asm-generic/errno.h> with <linux/errno.h>. <asm-generic/...> is supposed to be included from <asm/...> when arch-headers fall back into generic implementation.

2016-09-23Remove arch/${ARCH}/include/asm/errno.hMasahiro Yamada
Unlike Linux, nothing about errno.h is arch-specific in U-Boot. As you see, all of arch/${ARCH}/include/asm/errno.h is just a wrapper of <asm-generic/errno.h>. Actually, U-Boot does not export headers to user-space, so we just have to care about the consistency in the U-Boot tree. Now all of include directives for <asm/errno.h> are gone.

2016-09-23ext4: Use helper function to access group descriptor and its fieldsStefan Brüns
The descriptor size is variable, thus array indices are not generically applicable. The larger group descriptors also contain e.g. high parts of block numbers, which have to be read and written. Signed-off-by: Stefan Brüns <stefan.bruens@rwth-aachen.de>

2016-09-23ext4: Fix memory leak of journal buffer if block is updated multiple timesStefan Brüns
If the same block is updated multiple times in a row during a single file system operation, gd_index is decremented to use the same journal entry again. Avoid loosing the already allocated buffer. Signed-off-by: Stefan Brüns <stefan.bruens@rwth-aachen.de>
2016-09-23ext4: Correct block number handling, empty block vs. error codeStefan Brüns
read_allocated block may return block number 0, which is just an indicator a chunk of the file is not backed by a block, i.e. it is sparse. During file deletions, just continue with the next logical block, for other operations treat blocknumber <= 0 as an error. For writes, blocknumber 0 should never happen, as U-Boot always allocates blocks for the whole file. Reading already handles this correctly, i.e. the read buffer is 0-fillled. Not treating block 0 as sparse block leads to FS corruption, e.g. ./sandbox/u-boot -c 'host bind 0 ./sandbox/test/fs/3GB.ext4.img ; ext4write host 0 0 /2.5GB.file 1 ' The 2.5GB.file from the fs test is actually a sparse file.

2016-09-23ext4: remove duplicated block release code for extentsStefan Brüns
The data blocks are identical for files using traditional direct/indirect block allocation scheme and extent trees, thus this code part can be common. Only the code to deallocate the indirect blocks to record the used blocks has to be seperate, respectively the code to release extent tree index blocks. Actually the code to release the extent tree index blocks is still missing, but at least add a FIXME at the appropriate place. Signed-off-by: Stefan Brüns <stefan.bruens@rwth-aachen.de>

2016-09-23ext4: Avoid out-of-bounds access of block bitmapStefan Brüns
If the blocksize is 1024, count is initialized with 1. Incrementing count by 8 will never match (count == fs->blksz * 8), and ptr may be incremented beyond the buffer end if the bitmap is filled. Add the startblock offset after the loop. Remove the second loop, as only the first iteration will be done.

2016-09-23ext4: After completely filled group, scan next group from the beginningStefan Brüns
The last free block of a block group may be in its middle. After it has been allocated, the next block group should be scanned from its beginning. The following command triggers the bad behaviour (on a blocksize 1024 fs): ./sandbox/u-boot -c 'i=0; host bind 0 ./disk.raw ; while test $i -lt 260 ; do echo $i; setexpr i $i + 1; ext4write host 0:2 0 /X${i} 0x1450; done ; ext4write host 0:2 0 /X240 0x2000 ; ' When 'X240' is extended from 5200 byte to 8192 byte, the new blocks should start from the first free block (8811), but it uses the blocks 8098-8103 and 16296-16297 -- 8103 + 1 + 8192 = 16296.
