## SPDX-License-Identifier: GPL-2.0-only config SOC_AMD_COMMON_BLOCK_PSP bool help This option builds in the Platform Security Processor initialization functions. Do not select this directly in SoC code, select SOC_AMD_COMMON_BLOCK_PSP_GENx instead. config SOC_AMD_COMMON_BLOCK_PSP_GEN1 bool select SOC_AMD_COMMON_BLOCK_PSP help Used by the PSP in AMD systems before family 17h, e.g. stoneyridge. config SOC_AMD_COMMON_BLOCK_PSP_GEN2 bool select SOC_AMD_COMMON_BLOCK_PSP select SOC_AMD_COMMON_BLOCK_SMN help Used by the PSP in AMD family 17h, 19h and possibly newer CPUs. config SOC_AMD_PSP_SELECTABLE_SMU_FW bool help Some PSP implementations allow storing SMU firmware into cbfs and calling the PSP to load the blobs at the proper time. The soc/ should select this if its PSP supports the feature and each mainboard can choose to select an appropriate fanless or fanned set of blobs. Ask your AMD representative whether your APU is considered fanless. config SOC_AMD_COMMON_BLOCK_PSP_SPL bool help Select this option in the SoC's Kconfig to include the Security Patch Level (SPL) support code. This code will only send the actual SPL fuse update command to the PSP if the PERFORM_SPL_FUSING option is also selected. config PERFORM_SPL_FUSING bool "Send SPL fusing command to PSP" default n depends on SOC_AMD_COMMON_BLOCK_PSP_SPL help Send the Security Patch Level (SPL) fusing command to the PSP in order to update the minimum SPL version to be written to the SoC's fuse bits. This will prevent using any embedded firmware components with lower SPL version. If unsure, answer 'n' config SPL_TABLE_FILE string "SPL table file override" depends on SOC_AMD_COMMON_BLOCK_PSP_SPL help Provide a mainboard-specific Security Patch Level (SPL) table file override. The SPL file is required to support PSP FW anti-rollback and needs to be created by AMD. The default SPL file specified in the SoC's fw.cfg is in the corresponding folder of the amd_blobs submodule and applies to all boards that use the SoC without verstage on PSP. In the verstage on PSP case, a different SPL file is specific as an override via this Kconfig option. config HAVE_SPL_RW_AB_FILE bool "Have a separate mainboard-specific SPL file in RW A/B partitions" default n depends on SOC_AMD_COMMON_BLOCK_PSP_SPL depends on VBOOT_SLOTS_RW_AB help Have separate mainboard-specific Security Patch Level (SPL) table file for the RW A/B FMAP partitions. config SPL_RW_AB_TABLE_FILE string "Separate SPL table file override for RW A/B partitions" depends on HAVE_SPL_RW_AB_FILE config PSP_PLATFORM_SECURE_BOOT bool "Platform secure boot enable" depends on SOC_AMD_COMMON_BLOCK_PSP_GEN2 default n help Select this config to enable PSP Platform Secure Boot. Platform Secure Boot will automatically be fused on boot if the coreboot ROM is properly signed and can not be disabled once fused.

This position is relative to a 16MB flash window. If the flash size is smaller than 16MB it gets mapped at the top of that window. config AMD_FWM_POSITION_20000 bool "0x20000" config AMD_FWM_POSITION_420000 bool "0x420000" config AMD_FWM_POSITION_820000 bool "0x820000" config AMD_FWM_POSITION_C20000 bool "0xC20000" config AMD_FWM_POSITION_E20000 bool "0xE20000" config AMD_FWM_POSITION_F20000 bool "0xF20000" config AMD_FWM_POSITION_FA0000 bool "0xFA0000" endchoice config AMD_FWM_POSITION hex default 0x20000 if AMD_FWM_POSITION_20000 default 0x420000 if AMD_FWM_POSITION_420000 default 0x820000 if AMD_FWM_POSITION_820000 default 0xc20000 if AMD_FWM_POSITION_C20000 default 0xe20000 if AMD_FWM_POSITION_E20000 default 0xf20000 if AMD_FWM_POSITION_F20000 default 0xfa0000 if AMD_FWM_POSITION_FA0000
