From 8b14e1dff067195dca7a42321771437cb33a99e9 Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Tue, 29 Sep 2020 06:48:36 +0000 Subject: powerpc: Remove support for PowerPC 601 PowerPC 601 has been retired. Remove all associated specific code. CPU_FTRS_PPC601 has CPU_FTR_COHERENT_ICACHE and CPU_FTR_COMMON. CPU_FTR_COMMON is already present via other CPU_FTRS. None of the remaining CPU selects CPU_FTR_COHERENT_ICACHE. So CPU_FTRS_PPC601 can be removed from the possible features, hence can be removed completely.
