[PATCH 0/2] ARM: kexec: Add dtb kexce support

[Matthew Leach]

Currently the value of r2 that is passed to the new kernel when
performing a kexec() is hard coded to an address that is 16Kb before
the kernel image. A dtb file may be much larger and thus get corrupted
by the decompressor's page tables.

These patches, along with a set of kexec-tools patches, move the dtb
to a more sane location. The kernel will scan each segment for the dtb
magic within the first four bytes of each segment to identify the
physical address to pass through to the new kernel in r2.

  ARM: kexec: scan for dtb magic in segments
