From 99c45dee0ae62254be36a312d67764784450b564 Mon Sep 17 00:00:00 2001 From: Martin Roth Date: Sun, 15 Oct 2017 14:16:37 -0600 Subject: AMD GX2 boards & chips: Remove - using LATE_CBMEM_INIT MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit All boards and chips that are still using LATE_CBMEM_INIT are being removed as previously discussed. If these boards and chips are updated to not use LATE_CBMEM_INIT, they can be restored to the active codebase from the 4.7 branch. chips: cpu/amd/geode_gx2 northbridge/amd/gx2 southbridge/amd/cs5535 Mainboards: mainboard/amd/rumba mainboard/lippert/frontrunner mainboard/wyse/s50 Change-Id: I81c130f53bbfa001edbfdb7a878ef115757f620c Signed-off-by: Martin Roth Reviewed-on: https://review.coreboot.org/22025 Tested-by: build bot (Jenkins) Reviewed-by: Kyösti Mälkki --- src/cpu/amd/Kconfig | 1 -
