From f6af8943e23b8ffa27df6ddb8e4a654387be0cb6 Mon Sep 17 00:00:00 2001 From: Martin Roth Date: Sun, 15 Oct 2017 14:58:49 -0600 Subject: [PATCH] Intel i5000 board & 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: northbridge/intel/i5000 Mainboards: mainboard/supermicro/x7db8 mainboard/asus/dsbf Change-Id: I6614c0033b4439d196f26819998d3f85e6d11c00 Signed-off-by: Martin Roth Reviewed-on: https://review.coreboot.org/22030 Tested-by: build bot (Jenkins) Reviewed-by: Kyösti Mälkki --- src/cpu/intel/Kconfig | 1 -
