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)

This allows splitting EVA images (usually found in fritz devices). The
firmware will be split into a kernel and a separate rootfs partition.

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.

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.

We shouldn't read data directly into the header struct, as some devices
(e.g. Edimax) need more bytes due to some extra header.

Some devices have uImage headers after some extra headers (e.g. Edimax
devices). To support such cases our verify callback function should be
allowed to return header offset, not just a boolean value.

The board is already supported by OpenWrt. WNR1000v2/WNR1000v2-VC are
pretty much the same as WNR2000v3/WNR612v2, therefore the same
initialization code and flash layout is used.

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.

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.

The myloader partition parser code uses ifdef wrappers
to make the code usable on kernels below version 3.2.
All targets are using kernel 3.3 at least so the wraper
is not needed. Remove that.
