Intel i82830 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/intel/socket_mFCBGA479 northbridge/intel/i82830 Mainboards: mainboard/rca/rm4100 mainboard/thomson/ip1000 Change-Id: I9574179516c30bb0d6a29741254293c2cc6f12e9 Signed-off-by: Martin Roth <gaumless@gmail.com> Reviewed-on: https://review.coreboot.org/22032 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Kyösti Mälkki <kyosti.malkki@gmail.com>
