From e399b1a4e1d205bdc816cb550d2064f2eb1ddc4c Mon Sep 17 00:00:00 2001 From: Russell King Date: Mon, 17 Jan 2011 15:08:32 +0000 Subject: ARM: v6k: introduce CPU_V6K option 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.
