Change in ...coreboot[master]: [WIP] AGESA: Fix CAR_GLOBAL use for AP CPUs
by Kyösti Mälkki (Code Review) 31 Jul '20

31 Jul '20

Hello Marshall Dawson, I'd like you to do a code review. Please visit https://review.coreboot.org/c/coreboot/+/31361 to review the following change. Change subject: [WIP] AGESA: Fix CAR_GLOBAL use for AP CPUs ...................................................................... [WIP] AGESA: Fix CAR_GLOBAL use for AP CPUs The memory between _car_region_start .. _car_region_end has to be set up as WB in MTRRs for all the cores executing through bootblock, verstage and romstage. Otherwise CAR_GLOBALs may fail on AP CPUs. Fixes combination of CBMEM_CONSOLE=y with SQUELCH_EARLY_SMP=n, which previously did not boot at all. Does not fix family14.
