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

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.
