From 39c8bf2b3cc166a2a75111e4941cc5f7efbddc35 Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Tue, 17 Nov 2020 05:07:58 +0000 Subject: powerpc: Retire e200 core (mpc555x processor) There is no defconfig selecting CONFIG_E200, and no platform. e200 is an earlier version of booke, a predecessor of e500, with some particularities like an unified cache instead of both an instruction cache and a data cache. Remove it.
