Subject: [ARM] Remove yucky ifdefs to print "id(wb)BRR" suffix on CPU name

The "id(wb)BRR" suffix reports which CPU debugging options were (or
were not) selected at kernel build time.  Rather than have every
proc-*.S file implement this, report the control register value,
from which this information can be deduced.

Subject: [ARM] nommu: provide a way for correct control register value
 selection

Most MMU-based CPUs have a restriction on the setting of the data cache
enable and mmu enable bits in the control register, whereby if the data
cache is enabled, the MMU must also be enabled.  Enabling the data
cache without the MMU is an invalid combination.

However, there are CPUs where the data cache can be enabled without the
MMU.

In order to allow these CPUs to take advantage of that, provide a
method whereby each proc-*.S file defines the control regsiter value
for use with nommu (with the MMU disabled.)  Later on, when we add
support for enabling the MMU on these devices, we can adjust the
"crval" macro to also enable the data cache for nommu.

From 8799ee9f49f6171fd58f4d64f8c067ca49006a5d Mon Sep 17 00:00:00 2001
From: Russell King <rmk@dyn-67.arm.linux.org.uk>
Date: Thu, 29 Jun 2006 18:24:21 +0100
Subject: [ARM] Set bit 4 on section mappings correctly depending on CPU

On some CPUs, bit 4 of section mappings means "update the
cache when written to".  On others, this bit is required to
be one, and others it's required to be zero.  Finally, on
ARMv6 and above, setting it turns on "no execute" and prevents
speculative prefetches.

With all these combinations, no one value fits all CPUs, so we
have to pick a value depending on the CPU type, and the area
we're mapping.
