From 8fe11b8901a31d11990488c82bc23612589d57be Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Wed, 2 Sep 2015 10:40:24 +0900 Subject: powerpc: ppc4xx: remove lwmon5 support This has not been converted to Generic Board, so should be removed. (See doc/README.generic-board for details.) Remove CONFIG_LWMON5 references. (Also, remove undefined CONFIG_WD_MAX_RATE while I am here.)
