2021-02-01	drivers/intel/fsp2_0: Use coreboot postcar with FSP-T	Arthur Heymans
	Allow platforms to use the coreboot postcar code instead of calling into FSP-M TempRamExit API. There are several reasons to do this: - Tearing down CAR is easy. - Allows having control over MTRR's and caching in general. - The MTRR's set up in postcar be it by coreboot or FSP-M are overwritten later on during CPU init so it does not matter. - Avoids having to find a CBFS file before cbmem is up (this causes problems with cbfs_mcache) Change-Id: I6cf10c7580f3183bfee1cd3c827901cbcf695db7 Signed-off-by: Arthur Heymans <arthur@aheymans.xyz> Reviewed-on: https://review.coreboot.org/c/coreboot/+/48466 Reviewed-by: Patrick Georgi <pgeorgi@google.com> Reviewed-by: Angel Pons <th3fanbus@gmail.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
2020-10-28	soc/intel: deduplicate ACPI timer emulation	Michael Niewöhner
	The code for enabling ACPI timer emulation is the same for the SoCs SKL, CNL, ICL, TGL, JSL and EHL. Deduplicate it by moving it to common code. APL differs in not having the delay settings. However, the bits are marked as "spare" and BWG mentions there are no "reserved bit checks done". Thus, we can write them unconditionally without any effect. Note: The ACPI timer emulation can only be used by SoCs with microcode supporting CTC (Common Timer Copy) / ACPI timer emulation.

2019-11-05	soc/intel/common: Don't link CAR teardown in romstage	Arthur Heymans
	This is done in postcar stage. This also assumes CAR tear down will always be done in postcar stage.

2019-11-04	soc/intel/sgx: convert SGX and PRMRR devicetree options to Kconfig	Michael Niewöhner
	The devicetree is not made for user-choosable options, thus introduce Kconfig options for both SGX and the corresponding PRMRR size. The PRMRR size Kconfig has been implemented as a maximum value. At runtime the final PRMRR size gets selected by checking the supported values in MSR_PRMRR_VALID_CONFIG and trying to select the value nearest to the chosen one. When "Maximum" is chosen, the highest possibly value from the MSR gets used. When a too strict limit is set, coreboot will die, printing an error message.

2018-10-25	soc/intel: Consolidate FSP CAR setup and teardown code	Praveen hodagatta pranesh
	This patch adds following changes, - APL, CFL, DENVERTON soc's using same implementation to setup and teardown FSP CAR. Hence cache_as_ram_fsp.S from soc folder is cosolidated into one file and moved to common code CPU car folder. - exit_car_fsp.S is from APL, DNV soc folder is clubbed into one file and moved to common CPU car. - The new file apollolake/fspcar.c is addded to pass tempraminit parameters. - Coffee lake Soc uses FSPT to support Intel Security features like BootGuard verify boot and Measured boot. Add FSP CAR support for CFL by programming tempraminit parameters and add FSP_T_XIP default if FSP_CAR is selected. BUG= None TEST= Build for both CFL RVP11 & RVP8 and verified for successful CAR setup. Build for both leafhill and harcuvar platform by selecting CONFIG_FSP_CAR without errors.
