This patch has broken MPC8610.  I discovered it with git bisect.
After applying this patch, I get this error when I try to boot the
kernel:

   Uncompressing Kernel Image ... Error: inflate() returned -2
GUNZIP: uncompress, out-of-mem or overwrite error - must RESET board to recover

The latest U-Boot is worse - instead of displaying an error, I get a
machine check:

   Uncompressing Kernel Image ... Machine check in kernel mode.

machine check

My guess is that the machine check and the -2 error are related.  Does
anyone have a clue what the problem really is?
