Add more SPDX-License-Identifier tags

2016-01-19T13:31:21+00:00

In a number of places we had wordings of the GPL (or LGPL in a few
cases) license text that were split in such a way that it wasn't caught
previously.  Convert all of these to the correct SPDX-License-Identifier
tag.

nand: yaffs: Remove the "nand write.yaffs" command

2015-03-31T04:24:39+00:00

This command is only enabled by one board, complicates the NAND code,
and doesn't appear to have been functioning properly for several
years.  If there are no bad blocks in the NAND region being written
nand_write_skip_bad() will take the shortcut of calling nand_write()
which bypasses the special yaffs handling.  This causes invalid YAFFS
data to be written. See
http://lists.denx.de/pipermail/u-boot/2011-September/102830.html for
an example and a potential workaround.

U-Boot still retains the ability to mount and access YAFFS partitions
via CONFIG_YAFFS2.

nand: Add verification functions

2015-03-31T04:24:38+00:00

Add nand_verify() and nand_verify_page_oob().  nand_verify() verifies
NAND contents against an arbitrarily sized buffer using ECC while
nand_verify_page_oob() verifies a NAND page's contents and OOB.

nand: Remove unused read/write structures

2015-03-31T04:17:16+00:00

The use of the nand_write_options and nand_read_options structures were
removed in commit dfbf617ff055e4216f78d358b0867c548916d14b.  Remove the
now-unused structures too.

dfu, nand: before write a buffer to nand, erase the nand sectors

2013-06-24T23:17:23+00:00

before writing the received buffer to nand, erase the nand
sectors. If not doing this, nand write fails. See for
more info here:

http://lists.denx.de/pipermail/u-boot/2013-June/156361.html

Using the nand erase option "spread", maybe overwrite
blocks on, for example another mtd partition, if the
erasing range contains bad blocks.
So a limit option is added to nand_erase_opts()

mtd: resync with Linux-3.7.1

2013-05-31T22:12:03+00:00

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.
