Martin Roth has uploaded this change for review. ( https://review.coreboot.org/22030
Change subject: Intel i5000 board & chips: Remove - using LATE_CBMEM_INIT
......................................................................
Intel i5000 board & 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 4.8 branch.
chips:
northbridge/intel/i5000
Mainboards:
mainboard/supermicro/x7db8
mainboard/asus/dsbf
