This commit makes the kernel supply an AT_PLATFORM string that indicates what class of processor we are running on. Processors with the same set of user-level instructions and roughly the same instruction scheduling characteristics are given the same AT_PLATFORM value; for example, 821, 823 and 860 are all reported as "ppc823", and 7447, 7447A, 7448, 7450, 7451, 7455 are all called "ppc7450". The intention is that the AT_PLATFORM values match the values that gcc accepts for the -mcpu= option. For values which are numeric (e.g. -mcpu=750), "ppc" has been prepended. This also adds a PPC_FEATURE_BOOKE bit to the AT_HWCAP value and sets it for the 440 family and the Freescale 85xx family. Signed-off-by: Paul Mackerras --- Reading git-diff-tree failed
