      [ARM] Print details relevant to how we handle the cache · 2b4ae1f1
      由 Russell King 提交于 
      This replaces the original cache type decoding printks.  We now
indicate how we're treating the cache which we found, rather
than what we found.

      [ARM] Introduce new bitmask based cache type macros · c0e95878
      由 Russell King 提交于 
      Rather than trying to (inaccurately) decode the cache type from the
registers each time we need to decide what type of cache we have,
use a bitmask initialized early during boot.

Since the setup is a one-off initialization, we can be a little more
clever and take account of the CPU architecture as well.

Note that we continue to achieve the compactness on optimised kernels
by forcing tests to always-false or always-true as appropriate, thereby
allowing the compiler to do build-time code elimination.

      [ARM] Remove cache type printks · 90f1e084
      由 Russell King 提交于 
      The cache type register found in ARMv5 and later CPUs changes format
and meaning depending on the CPU architecture version.  Currently,
this code:
a) doesn't work for everything - Xscale's are identified as
   'unknown 5'.
b) is not able to tell whether the caches are VIVT or VIPT from the
   cache type.
c) prints rubbish on some ARMv6 and ARMv7+ CPUs.

The two solutions to this are:
1. Add yet more code to decode and print the various different register
   formats.
2. Remove the code altogther.

The code only exists to decode and print the cache parameters.
Increasing the complexity of it just for the sake of a few prinks
isn't worth it.
