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 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.
