      ARM: implement some Cortex-A9 errata workarounds · 0678587f

      Various errata exist in the Cortex-A9 CPU, and may be worked around by
      setting some bits in a CP15 diagnostic register. Add code to implement
      the workarounds, enabled by new CONFIG_ options.
      
      This code was taken from the Linux kernel, v3.8, arch/arm/mm/proc-v7.S,
      and modified to remove the logic to conditionally apply the WAR (since we
      know exactly which CPU we're running on given the U-Boot configuration),
      and use r0 instead of r10 for consistency with the rest of U-Boot's
      cpu_init_cp15().
