From d4efb330c1d87ac9f16be4e97b70797dcbe4e3bc Mon Sep 17 00:00:00 2001 From: Jonathan Zhang Date: Wed, 22 Jul 2020 12:39:40 -0700 Subject: soc/intel/xeon_sp/cpx: enable PLATFORM_USES_FSP2_2 CPX-SP FSP is FSP 2.2, so select PLATFORM_USES_FSP2_2. SKX-SP continues to select PLATFORM_USES_FSP2_0, as SKX-SP FSP is FSP 2.0. Correct DCACHE_RAM_BASE. Increase FSP_TEMP_RAM_SIZE, DCACHE_BSP_STACK_SIZE, and adjust DCACHE_RAM_SIZE accordingly. Thus the workaround of hardcoding StackBase and StackSize FSP-M UPD parameters is removed. Add CPX-SP soc implementation of soc_fsp_multi_phase_init_is_enable() to indicate that FSP-S multi phase init is not enabled, since it is not supported by CPX-SP FSP. TESTED=booted YV3 config A to target OS.
