2019-12-04binaryPI: Fix failing AP startupKyösti Mälkki
Fix regression with commit 5639736 binaryPI: Drop CAR teardown without POSTCAR_STAGE Occassionally (maybe 1 boot in 10) SMP lapic_cpu_init() fails with following errors in the logs of pcengines/apu2: CPU 0x03 would not start! CPU 0x03 did not initialize! The CPU number is sometimes 0x02, never seen 0x01. Work-around also suggests something to do with cache coherency and MTRRs that is really at fault. As a work-around return the BSP CAR teardown to use wbinvd instead of invd. These platforms do not support S3 resume so this is the easy work-around for the time being.

2019-11-27binaryPI: Drop CAR teardown without POSTCAR_STAGEKyösti Mälkki
The remaining (active) binaryPI boards moved away from BINARYPI_LEGACY_WRAPPER and have POSTCAR_STAGE now. As the cache_as_ram.S is also used with AGESA, this slightly reduces the codesize there for romstage and postcar as well. This commit is actually a revert for the vendorcode parts, AMD originally shipped the codes using 'invd' for the CAR teardown, but these were changed for coreboot due the convoluted teardown that used to happen with non-empty stack.

2019-02-14binaryPI: Fix cache coherency use for AP CPUsKyösti Mälkki
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 global variables may fail on AP CPUs. Fixes combination of CBMEM_CONSOLE=y with SQUELCH_EARLY_SMP=n, which previously did not boot at all for some cases.

2017-09-26AGESA: Implement POSTCAR_STAGEKyösti Mälkki
Move all boards that have moved away from AGESA_LEGACY_WRAPPER or BINARYPI_LEGACY_WRAPPER to use POSTCAR_STAGE. We use POSTCAR_STAGE as a conditional in CAR teardown to tell our MTRR setup is prepared such that invalidation without writeback is a valid operation.
