commit 073e1b509980cefe6f53c2d7fbbcd135df1e3924
Author: Andy Fleming <afleming@freescale.com>
Date: Tue Aug 14 10:32:59 2007 -0500
Fix initrd/dtb interaction
The original code would wrongly relocate the blob to be right before
the initrd if it existed. The blob *must* be within CFG_BOOTMAPSZ,
if it is defined. So we make two changes:
1) flag the blob for relocation whenever its address is above BOOTMAPSZ
2) If the blob is being relocated, relocate it before kbd, not initrd
