* ARM: correctly identify ARMv6 K/ZLucas Stach2017-03-031-0/+8
| | | | | | | | | | The ARMv6 K/Z derivatives have a v7 compatible MMU, but all other parts (including the cache handling) is still at v6. As we don't make use of the more advanced features of the v7 MMU in Barebox, it's okay to just override this to properly identify the CPU as ARMv6.

| * ARM: make cpu architecture detection available as static inline functionSascha Hauer2013-03-041-0/+43
| | | | | | | | | | | | | | | | | | When we have multi cpu support compiled in we need the cpu architecture early so that we can pick the correct cacheflush function. Make it available as static inline function and add a comment above it that this function normally should not be used. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* ARM: Add cpu_architecture() functionSascha Hauer2012-10-101-0/+60
Once we run on multiple SoCs we must know which arm architecture we are on. Add cpu_architecture() from the kernel to detect it. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
