[ARM] 5417/1: Set the correct cacheid for ARMv6 CPUs with ARMv7 style MMU 2009-03-03T12:11:26+00:00 Catalin Marinas catalin.marinas@arm.com 2009-03-03T10:44:12+00:00 b57ee99fab25dbc12150fe66fe54dc52bc6de784 The cacheid_init() function assumes that if cpu_architecture() returns 7, the caches are VIPT_NONALIASING. The cpu_architecture() function returns the version of the supported MMU features (e.g. TEX remapping) but it doesn't make any assumptions about the cache type.

The unwinding information consists of an index with a pair of words per function and a table with unwinding instructions.

Let's keep only the later to directly populate the permanent version from arm_add_memory(). Also move common validation tests between the MMU and non-MMU cases into arm_add_memory() to remove some duplication. Protection against overflowing the membank array is also moved in there in order to cover the kernel cmdline parsing path as well.
