70524883b0 microblaze: Support system with WB cache
WB cache use different instruction that WT cache but the major code
is that same. That means that wdc.flush on system with WT cache
do the same thing as before.

You need newer toolchain with wdc.flush support.

It is more accurate to show that caches are OFF instead of FAIL.

8125c980cc microblaze: Fix interrupt handler code
It is better to read ivr and react on it than do long parsing from
two regs. Interrupt controller returs actual irq number.

5bbcb6cf22 microblaze: Move timer initialization to board.c
I would like to handle case where system doesn't contain
intc that's why I need timer initialization out of intc code.

cc53690e05 microblaze: Fix irq.S code
It is ancient code. There is possible to save several instructions
just if we use offset instead of addik

398b1d57a6 microblaze: Add FDT support
This patch adds FDT (flattened device tree) support to microblaze arch.

Tested with Linux arch/microblaze kernels with and without compiled in
FDT on Xilinx ML506 board.

2a72e9ed18 ppc4xx: Add option for PPC440SPe ports without old Rev. A support
The 440SPe Rev. A is quite old and newer 440SPe boards don't need support
for this CPU revision. Since removing support for this older version
simplifies the creation for newer U-Boot ports, this patch now enables
440SPe > Rev. A support by creating the CONFIG_440SPE_REVA define. By
defining this in the board config header, Rev. A will still be supported.
Otherwise (default for newer board ports), Rev. A will not be supported.

819833af39 Move architecture-specific includes to arch/$ARCH/include/asm
This helps to clean up the include/ directory so that it only contains
non-architecture-specific headers and also matches Linux's directory
layout which many U-Boot developers are already familiar with.

ea0364f1bb Move lib_$ARCH directories to arch/$ARCH/lib
Also move lib_$ARCH/config.mk to arch/$ARCH/config.mk

This change is intended to clean up the top-level directory structure
and more closely mimic Linux's directory organization.
