[PATCH 04/14] ARM: v6k: introduce CPU_V6K option
From: Will Deacon <hidden>
Date: 2011-01-18 10:36:08
Hi Russell,
Introduce a CPU_V6K configuration option for platforms to select if they have a V6K CPU core. This allows us to identify whether we need to support ARMv6 CPUs without the V6K SMP extensions at build time. Currently CPU_V6K is just an alias for CPU_V6, and all places which reference CPU_V6 are replaced by (CPU_V6 || CPU_V6K). Select CPU_V6K from platforms which are known to be V6K-only.

Can we change the tune target to 1176 for v6k?

Can we lose the CPU_V6 check here? RWFO is only required for 11MPCore so I think we just need to check CPU_V6K && SMP. Will
