4f3cbd79af microblaze: Define readq and writeq IO helper function
Some drivers check if readq/writeq functions are defined.
If not internal driver functions are used which cause
compilation failures.

17578ea198 microblaze: Define read/write{b,w,l}_relaxed MMIO
More and more ARM specific drivers is using MMIO
readX/writeX_relaxed IO functions and Microblaze can
shared some drivers with ARM too.

This patch adds relaxed IO accessor macros
to prevent compilation failures.

c1120542b9 microblaze: Add support for CCF
Add support for CCF for Microblaze.

Old binding:
system_timer: system-timer@41c00000 {

	...
}

New binding:
system_timer: system-timer@41c00000 {
	clocks = <&clk_bus>;
	...
}

Both should be supported for a while

Microblaze clock binding:
clocks {
	#address-cells = <1>;
	#size-cells = <0>;
	clk_bus: bus {
		#clock-cells = <0>;
		clock-frequency = <75000000>;

		compatible = "fixed-clock";

    from Ben Hutchings.

    hash, if provided.  From Tom Herbert.

93ea02bb84 arch: Clean up asm/barrier.h implementations using asm-generic/barrier.h
We're going to be adding a few new barrier primitives, and in order to
avoid endless duplication make more agressive use of
asm-generic/barrier.h.

Change the asm-generic/barrier.h such that it allows partial barrier
definitions and fills out the rest with defaults.

There are a few architectures (m32r, m68k) that could probably
do away with their barrier.h file entirely but are kept for now due to
their unconventional nop() implementation.

32df8dca50 of: remove HAVE_ARCH_DEVTREE_FIXUPS
HAVE_ARCH_DEVTREE_FIXUPS appears to always be needed except for sparc,
but it is only used for /proc/device-teee and sparc does not enable
/proc/device-tree. So this option is redundant. Remove the option and
always enable it. This has the side effect of fixing /proc/device-tree
on arches such as arm64 which failed to define this option.
