soc/intel/{apl,cnl,dnv,skl}: Skip ucode loading by FSP-T
It is a requirement for Firmware to have Firmware Interface Table (FIT), which contains pointers to each microcode update. The microcode update is loaded for all logical processors before reset vector. FSPT_UPD.MicrocodeRegionBase and FSPT_UPD.MicrocodeRegionLength are input parameters to TempRamInit API. If these values are 0, FSP will not attempt to update microcode. Since Gen-4 all IA-SoC has FIT loading ucode even before cpu reset in place hence skipping FSP-T loading ucode after CPU reset options. Also removed unused kconfig CONFIG_CPU_MICROCODE_CBFS_LOC and CONFIG_CPU_MICROCODE_CBFS_LEN Change-Id: I3a406fa0e2e62e3363c2960e173dc5f5f5ca0455 Signed-off-by: Subrata Banik <subrata.banik@intel.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/37187 Reviewed-by: Arthur Heymans <arthur@aheymans.xyz> Reviewed-by: David Guckian Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
