All the maintained platforms are now in arch/powerpc, so the old
arch/ppc stuff can now go away.

This patch removes all self references and fixes references to files
in the now defunct arch/ppc64 tree. I think this accomplises
everything wanted, though there might be a few references I missed.

platfom bus.
This patch only deals with the serial port definitions as there is no
support for any other xilinx IP cores in the kernel tree at the moment.
Board specific configuration moved out of virtex.[ch] and into the
xparameters.h wrapper.
This also prepares for the transition to the flattened device tree model.
When the bootloader provides a device tree generated from an xparameters.h
files, the kernel will no longer need xparameters/*. The platform bus will
get populated with data from the device tree, and the device drivers will
be automatically connected to the devices. Only the bootloader (or
ppcboot) will need xparameters directly.

In 2.6.14, we had the following definition of _GLOBAL() in
include/asm-ppc/processor.h:
#define _GLOBAL(n)\
.stabs __stringify(n:F-1),N_FUN,0,0,n;\
.globl n;\
n:
In 2.6.15, as part of the great powerpc merge, we moved this definition to
include/asm-powerpc/ppc_asm.h, where it appears (to 32-bit code) as:
#define _GLOBAL(n) \
.text; \
.stabs __stringify(n:F-1),N_FUN,0,0,n;\
.globl n; \
n:
Mostly, this is fine. However, we also have the following, in
arch/ppc/boot/common/util.S:
.section ".relocate_code","xa"
[...]
_GLOBAL(flush_instruction_cache)
[...]
_GLOBAL(flush_data_cache)
[...]
The addition of the .text section definition in the definition of
_GLOBAL overrides the .relocate_code section definition. As a result,
these two functions don't end up in .relocate_code, so they don't get
relocated correctly, and the boot fails.
There's another suspicious-looking usage at kernel/swsusp.S:37 that
someone should look into. I did not exhaustively search the source
tree, though.
The following is the minimal patch that fixes the immediate problem.
I could easily be convinced that the _GLOBAL definition should be
modified to remove the ".text;" line either instead of, or in addition
to, this fix.

Modifies serial_init to get base baud rate from the rs_table entry instead
of BAUD_BASE. This patch eliminates duplication between the
SERIAL_PORT_DFNS macro and BAUD_BASE. Without the patch, if a port set the
baud rate in SERIAL_PORT_DFNS, but did not update BASE_BAUD, the BASE_BAUD
value would still be used.

In the flush and invalidate bootcode on PPC4xx we were accidentally using
the wrong instruction. Use cmplw, which reads from a register like we
want.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
