mtd: nand: imx-bbm: use raw reading when checking for factory BBM ...

This is necessary to prevent the imx_nand_bbm command to bail out
on ECC errors which leaves the device without BBT.

Also simplify buffer management: Use on-stack buffer instead of malloc.

ARM: boot: add prepend option for board specific ATAGs ...

Board specific ATAGs might be passed to vendor provided kernels via the
ARM_BOARD_APPEND_ATAG option. In this case, the board specific ATAGs will
be appended to the end of the ATAG list.
Anyway, some vendor provided kernels might crop the ATAG list at ATAG_MEM,
also chopping off the board specific ATAGs, see linux squash_mem_tags() as
reference. The Kindle-3 kernel is one example.

This conflict might be solved by a) making ATAG_MEM optional which might break
the existing behavour around squash_mem_tags() or b) by allowing the insertion
of board specific ATAGs in front of ATAG_MEM which violates the requirement
from Documentation/arm/Booting to order ATAGs by increasing address.

Add option to insert board specific ATAGs in front of ATAG_MEM.
