We have many variants of the same bitops.h file. Consistently
use the same file for all architectures which completely use
the generic bitops versions.
Some architectures had static inline versions of functions
identically to the generic versions, these are removed and
the generic versions are used directly now.
Also several architectures depend on the generic find_*_bit
functions but didn't have the GENERIC_FIND_NEXT_BIT Kconfig
option selected. This is added where needed.

The OpenRISC architecture specification v1.0 defines
new SPR registers. This patch adds registers definition
for group 0 and update bit definitions for the CPU
configuration register.

openrisc does nothing special in the io accessors, so use the generic
ones as the kernel.

Change function remap_range in arm architecture to make it
global accessable. For example command 'memtest' can change
pte flags to enable or disable cache.
Add dummy function for others architectures that doesn't
have mmu or pte support.

The FSF address has changed in the past. Instead of updating it
each time the address changes, just drop it completely treewide.

Some drivers call dma_inv_range() on buffers, on arm these buffers must
be cache line aligned. This patch introduces a generic dma_alloc,
dma_free. Archs can implement in their own functions in "asm/dma.h" and add a:
#define dma_alloc dma_alloc
#define dma_free dma_free
On all other archs the generic versions, which translate into xmalloc
and free are used.

OpenRISC is the original flagship project of the OpenCores community.
This project aims to develop a series of general purpose open source
RISC CPU architectures.
A team from OpenCores provided the first implementation, the OpenRISC
1200, written in the Verilog hardware description language.
Even though I should have created an mach-or1200 directory, it is not
necessary for now. The OpenRISC 1200 CPU is the only one available and
it will be for some time.
