2020-11-07	soc/amd/common/psp: expand CPU family names in Kconfig help text	Felix Held
	Expand fam17h to family 17h to make the help text slightly easier to understand and add family 19h to the description of SOC_AMD_COMMON_BLOCK_PSP_GEN2.

2020-04-13	soc/amd/common/psp: Split mailbox support into v1 and v2	Marshall Dawson
	Family 17h redefines the PSP command and status, and therefore the steps required to send commands via the mailbox. Convert the existing version into a v1 and add a v2. New Kconfig options allow the soc to choose v1 vs. v2. The v2 PSP begins responding to the mailbox command when the full bit range is written. Define the new mailbox as a union of a u32 and a structure. Additional PSP details may be found in the NDA publication (#55758) AMD Platform Security Processor BIOS Architecture Design Guide for AMD Family 17h Processors Change the existing two soc functions that return pointers to void pointers.

2017-11-08	soc/amd/common/psp: Add command to load fw blobs	Marshall Dawson
	An upcoming PSP firmware change will allow coreboot to load the two SMU firmware blobs (one runs in SRAM and the other in DRAM). The traditional method is for the PSP to control most of the process, e.g. loading the SRAM version prior to releasing the x86 reset. Add a new command that can instruct the PSP to load a firmware blob from a location in the flash. The definition for commands 19 and 1a differ from others in that they do not use a command/response buffer. Instead, the PSP will look in the command/response pointer registers directly for the blob's address.

2017-07-02	soc/amd/common: Add initial support for AMD PSP	Marshall Dawson
	Add files for supporting the BIOS->PSP communication not covered by AGESA. The first command implemented notifies the PSP that DRAM is ready. This patch also introduces the amd/common/block directory structure similar to intel/common/block.
