Remove ancient Kconfig option for consistent code.
MMU uses cache inhibit pages.
noMMU uses UNCACHE SHADOW feature where is used double ram size.
For example:
Physical ram is 256MB and cache are setup to cover the same size.
But if you setup in HW that size is 512MB and cache covers 256MB
than you can use adresses from 256-512MB without caches and
correspond with 0-256MB with cache. That's why I am using
dcache base/high addresses to find out uncache area.

For copy was used r7 register when CONFIG_CMDLINE_BOOL option
is enabled. But r7 stores pointer to fdt that's why machine_early_init
not detect compiled-in DTB.
I also moved kernel PID setup to have TLB init in one block

This patch is based on powerpc patch
64f16502475ddf663169369fffff6da9b10ea9fb
We did some cleanups and removed powerpc parts.
There is one new debug early listing function too.
Exclude function is only in Debug options.
We tested in on custom board.

There are two parts of changes. The first is just enable
PCI in Makefiles and in Kconfig. The second is the rest of
missing files. I didn't want to add it with previous patch
because that patch is too big.
Current Microblaze toolchain has problem with weak symbols
that's why is necessary to apply this changes to be possible
to compile pci support.
Xilinx knows about this problem.

Add DMA support for Microblaze. There are some part of this new feature:
1. Basic DMA support
2. Enable DMA debug option
3. Setup notifier
Ad 1. dma-mapping come from powerpc and x86 version and it is based on
generic dma-mapping-common.h
Ad 2. DMA support debug features which is used in generic file.
For more information please look at Documentation/DMA-API.txt
Ad 3. notifier is very important to setup dma_ops. Without this part
for example ll_temac driver failed because there are no setup dma operations.

btrfs inialize rb trees in quite a number of places by settin rb_node =
NULL; The problem with this is that 17d9ddc72fb8bba0d4f678 in the
linux-next tree adds a new field to that struct which needs to be NULL for
the new rbtree library code to work properly. This patch uses RB_ROOT as
the intializer so all of the relevant fields will be NULL'd. Without the
patch I get a panic.

The smsgiucv_app driver registers a callback with the smsgiucv driver
to receive z/VM CP special messages (SMSG) starting with "APP".
When the callback is called for special messages, the driver creates
an uevent for the received message. The uevent consists of additional
environment data containing the message prefix ("APP"), message sender,
and message content.
udev rules can be used to trigger application specific actions through
matching the content or sender of the special message.

The device driver must allocate memory for IUCV buffers with GFP_DMA,
because IUCV cannot address memory above 2GB (31bit addresses only).
Because the IUCV ignores the higher bits of the address, sending and

Before you can read or write from the i6300esb memeory mapped registers,
you need to unlock these. This is done by writing the magic numbers 0x80
and 0x86 to the reload register. The size of the reload register is 32bit
though.
Also binary 11 is hex 0x03 and not 0x11.

Create patch_hdmi.c to hold common code from intelhdmi and nvhdmi.
For now the patch_hdmi.c file is simply included by patch_intelhdmi.c
and patch_nvhdmi.c, and does not represent a real codec.
There are no behavior changes to intelhdmi. However nvhdmi made several
changes when copying code out of intelhdmi, which are all reverted in
this patch. Wei Ni confirmed that the reverted code actually works fine.
