1a57ce0c03 kernel: mtdsplit: add missing digest field to Seama header
Seama format has 2 similar headers: container (seal) header and entity
header. The first one has size always set to 0 and doesn't contain MD5
digest.

When dealing with Seama on a flash we deal directly with an entity. You
can see mtdsplit_parse_seama reads from offset 0 and expects entity to
be there. Seama container is used by bootloader / interface only which
extract entity out of it and flash it.

That said we should fix our header struct. This is important as we
calculate possible rootfs offset assuming it may be placed right after
Seama entity. So far calculate offset was always 16B too low.

9220dd5d36 kernel: mtdsplit: support Seama entity with UBI
Some D-Link routers (e.g. DIR-885L) have NAND and use Seama format. It
means OpenWrt will want to have UBI in Sseama entity and should be able
to detect it.

e1491b341b kernel: mtdsplit: modify rootfs helpers to provide partition type
Our mtdsplit parsers may want to create partition with name choice based
on partition file system (e.g. SquashFS vs. JFFS2). This patch allows
passing extra argument pointing to variable that will be set properly.

7703e14bc4 kernel: mtdsplit_squashfs: Align with the erase-block size
On most image types the rootfs ends at an erase-block. However, at least
with brnImages this is not the case: while the partitions are aligned
with the erase-block size there is a 12 byte footer at the end of the
partition which must not be touched by any filesystem. This lead to a
rootfs_data partition which was not aligned properly (and thus ended up
being readonly):
	0x000000480000-0x00000085a800 : "rootfs_data" (128 KiB EB)

bdd2772f1d kernel: mtdsplit: add support for brnImages
This adds brnImage (used with the brnboot bootloader) firmware parsing
support. brnboot verifies the integrity of the firmware stored on the
"Code Image" partitions by looking at the 12 byte footer at the very end
of the partition. This footer contains the checksum of the original
brnImage (kernel + rootfs/squashfs) and must not be touched (by our JFFS2
rootfs_data - otherwise the image will not be bootable anymore).

Big thanks to Mathias Kresin for analyzing the brnImage structure and
finding out the information how to keep images valid even when adding a
nested rootfs_data partition.

9a863f803e kernel: mtdsplit: add support for FIT image
If this option is enabled, the FIT image format will be detected and
split by the mtdsplit code. Detection is based upon the FDT magic, which
will trigger the parsing and detection of the rootfs, ending-up in the
creation of the 2 new partitions.

c9813699b6 kernel: add own Kconfig for OpenWrt mtdsplit drivers
There are pretty many OpenWrt patches against mtd subsystem resulting
in a bit of mess and growing maintenance cost.
My idea is to use an extra "mtdsplit" directory with OpenWrt specific
files (including Kconfig).
This is the first step to achieve this. This patch adds a "mtdsplit"
directory with Kconfig and replaces 4 patches with a single one.

c09007c1af kernel/generic: modify mtd related patches for 3.14
Function register_mtd_parser always returned 0 (at least since v3.3)
before being changed to return void in v3.14-rc1~65^2~93 (mtd: make
register_mtd_parser return void), so it's not needed to check the
return value of this function. Also add __init flag to caller.

This fix compile errors in 3.14 kernel like:
drivers/mtd/mtdsplit_seama.c: In function 'mtdsplit_seama_init':
drivers/mtd/mtdsplit_seama.c:99:2: error: void value not ignored as it ought to be
  return register_mtd_parser(&mtdsplit_seama_parser);

This reverts r38197.

The automatically created firmware partition includes
the partition_table partition. Apart from the partition
table, this partition contains sensitive data on some
Compex devices which data can be destroyed when the
firmware partition gets modified. Revert the change to
prevent that.
