AMD GX2 boards & chips: Remove - using LATE_CBMEM_INIT
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 <gaumless@gmail.com> Reviewed-on: https://review.coreboot.org/22025 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Kyösti Mälkki <kyosti.malkki@gmail.com>
