2020-11-30	soc/amd/common: simplify conditionals in Makefiles	Felix Held
	If there are multiple statements that are conditional on the same Kconfig option, group them and move the condition check around the statement. If there's only one statement depending on one condition, use the short form instead.

2020-04-16	soc/amd/psp: Add SmmInfo command	Marshall Dawson
	Implement the MboxBiosCmdSmmInfo function to inform the PSP of the SoC's SMM configuration. Once the BootDone command is sent, the PSP only responds to commands where the buffer is in SMM memory. Set aside a region for the core-to-PSP command buffer and the PSP-to-core mailbox. Also add an SMM flag, which the PSP expects to read as non-zero during an SMI. Add calls to soc functions for the soc to populate the trigger info and register info (v2 only). Add functions to set up the structures needed for the SmmInfo function in Picasso support. Issue a SW SMI, and add a new handler to call the new PSP function.

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.

2020-04-02	soc/amd/common/psp: Move early init to soc	Felix Held
	The initialization code in common//psp is very specific to Family 15h. Move this to the stoneyridge directory.

2017-11-14	soc/amd/stoneyridge: Load SMU fimware using PSP	Marshall Dawson
	Add the ability to locate the SMRAM-based SMU firmware early and call the PSP library to load it prior to DRAM initialization. This is currently placed in bootblock to ensure the blob is loaded before any reset occurs. Add similar functionality in ramstage for SMU FW2 to the hook already in place for running AmdInitEnv. Rename the hook to make more sense. This patch was tested using a pre-released PSP bootloader on a google/kahlee system. Leave the option unused until the bootloader is ready.

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.
