From 832325c18d1d68e0ee46810f788421865f6372d9 Mon Sep 17 00:00:00 2001 From: Alexey Brodkin Date: Tue, 3 Feb 2015 13:58:10 +0300 Subject: arc: remove CPU hard-coded selection from board description in include/configs With switch to Kconfig we only need very board-specific descriptions in include/configs. CPU selection is performed with either defconfig or manually via menuconfig.

Before that change we relied on minimal configuration but now we may use specific features of each CPU. Moreover allows us to escape manual selection of options that exist in both CPUs but may have say different version like MMUv2 in ARC750D vs MMUv3 in ARC770D.
