2020-07-15selftests/powerpc: Use proper error code to check fault addressHaren Myneni
ERR_NX_TRANSLATION(CSB.CC=5) is for internal to VAS for fault handling and should not used by OS. ERR_NX_AT_FAULT(CSB.CC=250) is the proper error code should be reported by OS when NX encounters address translation failure. This patch uses CC=250 to determine the fault address when the request is not successful.
