[PATCH 0/4] Support for device-tree appended to zImage

[bones@secretlab.ca (John Bonesio)]

Hi Shawn,

I'm using Grant's tree with Nicolas Pitre's patch to the compressed
image wrapper. His patches went out to the ARM list and I'm told they
were accepted. These patches may not yet be in Grant's tree. These
patches are titled:

[PATCH 1/2] ARM: improvements to compressed/head.S
[PATCH 2/2] ARM: remove the 4x expansion presumption while decompressing
the kernel

Grant, is there a branch in your tree that people should be using, or
should be they applying both sets of patches?
