b907097291 kernel: mtdsplit: wrgg: Support big and little endian
The WRGG images exist in both big and little endian variants,
as can be seen from the image generator in
tools/firmware-utils/src/mkwrggimg.c, you either pass
the "-b" flag or not. The D-Link DIR-685 is using little
endian images so we need to support splitting these.

Detect endianness like this: if the kernel entity size
gets silly big (bigger than the flash memory) we are
probably using the wrong endianness.

Example: my kernel of 0x0067ff64 was switched around by
wrong endianness and detected as 0x64ff67a0 (the actual
size in swapped endianness + header 0xa0).

74f891752b generic: make mtdsplit-tplink.c honor rootfs offset
The splitter ignored the rootfs offset from the header, probably
because until c1e6e61 it was invalid.

This patch fixes the splitter to use the now correct header data.

Regarding target/linux/ar71xx/files/drivers/mtd/tplinkpart.c,
this particular splitter "falls back" to the correct rootfs offset
reading and as such it doesn't need to be updated, although it will
report a kernel partition length that can be larger than the actual
length as it assumes that partition fills the entire segment up to
the rootfs partition.

890daca9e2 kernel: mtdsplit: Add support for Mikrotik NOR firmware
The RouterBOOT bootloader does not care where the kernel lives in the SPI
flash, all that matters is that the kernel is wrapped in the custom yaffs
container as generated by kernel2minor.

This container has a fixed signature as follows:
00000000  00 00 00 01 00 00 00 01  ff ff 6b 65 72 6e 65 6c  |..........kernel|

This patch adds mtdsplit support for identifying that signature and
triggering the search for the rootfs. rootfs is expected at EB boundary since
we use wget mtd_find_rootfs_from(). We make no use of the yaffs file size
field because it contains invalid data in the image generated by kernel2minor.

fd62fa752b ar71xx: Add support for Netgear WNR2000v1
This patch adds supports for the WNR2000v1 board with 4MB flash, and
produces device-specific factory, rootfs, and sysupgrade files for the
WNR2000v1. This board is errorneously claimed as supported on the OpenWRT
wiki as AP81, but AP81 image would not work because of APT81 image
requiring having 8MB of flash, while WNR2000v1 has only 4MB.

The image requires the u-boot bootloader to be modified to fuhry's
bootloader first.

Short specification:

- CPU: Atheros AR9132
- 4x 10/100 Mbps Ethernet, 1x WAN 10/100 Mbps
- 4 MB of Flash
- 32 MB of RAM
- UART header (J1) on board
- 1x button

Factory/Initial flash instructions:

- Set up a TFTP server on your local machine.
- Download the uImage for ar71xx-generic and the rootfs image for
  ar71xx-generic-wnr2000 and save in the tftp server root.
- Gain serial access to the router via the UART port (telnetenable over
  the network only won't work!).
- Upgrade the u-boot bootloader to fuhry's version by running the
  script: http://fuhry.com/b/wnr2000/install-repart.sh
- When the router restarts, interrupt u-boot and gain access to u-boot command line.
- Repartititon the board and flash initial uImage and rootfs as follow.

Commands to type in u-boot:

	# tells u-boot that we have a tftp server on 192.168.1.10
	setenv serverip 192.168.1.10

	# tells u-boot that the router should take the address 192.168.1.1
	setenv ipaddr 192.168.1.1

	# erase the region from 0x050000-0x3f0000
	erase 0xbf050000 +0x3A0000

	# loads sqfs.bin on TFTP server, and put it to memory address 0x81000000
	tftpboot 0x81000000 sqfs.bin
	# it will tell you the length of sqfs.bin in hex, let's say ZZZZZZ
	# copy bit by bit 0xZZZZZZ bytes from offset 0x050000
	cp.b 0x81000000 0xbf050000 0xZZZZZZ

	# same to the uImage.bin, write it right next to sqfs.bin
	# again, 0xYYYYYY is the length that tftpboot reports
	tftpboot 0x81000000 uImage.bin
	cp.b 0x81000000 0xbf2a0000 0xYYYYYY

	# We need to tell the kernel what board it is booting into, and where to find the partitions
	setenv bootargs "board=WNR2000 console=ttyS0,115200 mtdparts=spi0.0:256k(u-boot)ro,64k(u-boot-env)ro,3712k(firmware),64k(art)ro rootfstype=squashfs,jffs2 noinitrd"

	# Tell u-boot where to find the uImage
	setenv bootcmd "bootm 0xbf2a0000"

	# Tell u-boot to save parameters to the u-boot-env partitions
	saveenv

	# Reset the board
	reset

Tested on:

- WNR2000v1 board.
- Initial flash works.

Known bugs:

- I don't know why factory image doesn't work on initial flash on stock
  firmware in u-boot recovery mode while it should.
- Sysupgrade does not yet work, if you do -f it will mess up your
  installation (requiring a reinstall of sqfs and uImage).

magic and the type field is set to kernel as usual.

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.

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.
