Fix initrd booting
I thought it might be easier for you to pull from a repository instead
of applying the patch directly.

Fix initrd booting
The device tree needs to be passed to Linux within CFG_BOOTMAPSZ.
The current code places the device tree right before the initrd
if it exists, and that will usually be closer to the end of
memory. Instead, we should always put the device tree right
before the bd_info structure, thus ensuring it is within
CFG_BOOTMAPSZ.
We do, however, allow for FDTs in uImages to shoot themselves in
the foot by requesting a location outside of CFG_BOOTMAPSZ.
