This patch merges platform codes.  systemcfg->platform is no longer used,
systemcfg use in general is deprecated as much as possible (and renamed
_systemcfg before it gets completely moved elsewhere in a future patch),
_machine is now used on ppc64 along as ppc32.  Platform codes aren't gone
yet but we are getting a step closer. A bunch of asm code in head[_64].S
is also turned into C code.

Building a PowerMac kernel with ARCH=powerpc causes a bunch of warnings,
this fixes some of them

Mostly this involves adding #include <asm/smp.h>, since that defines
things like boot_cpuid[_phys] and [gs]et_hard_smp_processor_id, which
are SMP-related but still needed on UP.  This incorporates fixes
posted by Olof Johansson and Heikki Lindholm.

This moves rtas-proc.c and rtas_flash.c into arch/powerpc/kernel, since
cell wants them as well as pseries (and chrp can use rtas-proc.c too,
at least in principle).  rtas_fw.c is gone, with its bits moved into
rtas_flash.c and rtas.c.

This splits arch/ppc64/kernel/rtas.c into arch/powerpc/kernel/rtas.c,
which contains generic RTAS functions useful on any CHRP platform,
and arch/powerpc/platforms/pseries/rtas-fw.[ch], which contain
some pSeries-specific firmware flashing bits.  The parts of rtas.c
that are to do with pSeries-specific error logging are protected
by a new CONFIG_RTAS_ERROR_LOGGING symbol.  The inclusion of rtas.o
is controlled by the CONFIG_PPC_RTAS symbol, and the relevant
platforms select that.

In preparation for merging processor.h, this adds some explicit

This patch corrects the printing of progress indicators to the op
panel on p/iSeries ppc64 systems.  Each discrete reference code should
begin with a form feed char to clear the op panel, and the first and
second lines should be separated with a CR/LF sequence.  Padding with
spaces is not necessary.

Also, capitalize the hex value printed on the first line, to be
consistent with the values printed by firmware, service processor,
etc.

It turns out that there's an ibm,form-feed property; this patch uses
it in the pSeries-specific progress routine.  This patch also checks
the number of rows and the specific width of each row (the second row
on power5 systems can actually hold 80 characters).  If the displayed
text is too wide for the physical display, it can be viewed in the ASM
menus, or by selecting option 14 on the op panel.

The pSeries_progress function is called from some places in the rtas code,
which may also be used by non-pSeries platforms.
Though pSeries is currently the only platform type that implements
display-character, the code is actually generic enough to be part of
the rtas subsystem.

I hit a bug here because the generic rtas code tried calling ppc_md.progress,
which points to an __init function on most platforms.

We could also clear the ppc_md.progress pointer when freeing the init memory
to make it more explicit that ppc_md.progress must not be called after
bootup.

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!
