Commit 0fd7ef1f authored by Konrad Eisele's avatar Konrad Eisele Committed by David S. Miller

sparc,leon: Introduce the sparc-leon CPU type.

Add sparc_leon enum, M_LEON|M_LEON3_SOC machine. Add compilation of
leon.c in mm and kernel
if CONFIG_SPARC_LEON is defined. Add sparc_leon dependent
initialization to switch statements + head.S.
