From: Christophe Leroy Date: Sat, 17 Nov 2018 10:25:02 +0000 (+0000) Subject: powerpc: change CONFIG_PPC_STD_MMU_32 to CONFIG_PPC_BOOK3S_32 X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=68289ae935da5a8488c0268111631f644d27b683;p=openwrt%2Fstaging%2Fblogic.git powerpc: change CONFIG_PPC_STD_MMU_32 to CONFIG_PPC_BOOK3S_32 Today we have: config PPC_BOOK3S_32 bool "512x/52xx/6xx/7xx/74xx/82xx/83xx/86xx" [depends on PPC32 within a choice] config PPC_BOOK3S def_bool y depends on PPC_BOOK3S_32 || PPC_BOOK3S_64 config PPC_STD_MMU def_bool y depends on PPC_BOOK3S config PPC_STD_MMU_32 def_bool y depends on PPC_STD_MMU && PPC32 PPC_STD_MMU_32 is therefore redundant with PPC_BOOK3S_32. In order to make the code clearer, lets use preferably PPC_BOOK3S_32. This will allow to remove CONFIG_PPC_STD_MMU_32 in a later patch.
