[U-Boot-Users] [PATCH 3/3] 8xx: Add OF support to adder87x board

[Bryan O'Donoghue]

Fits in with recent work done in Linux.

Adds u-boot support in conjunction with two previous patches to boot a Linux
uImage in conjunction with a .dtb generated from the in-tree adder875-uboot.dts
in recent PowerPC Linux kernel patches.

Works too !
