2020-07-08	soc/amd/picasso: add psp_verstage	Martin Roth
	This is the main code for building coreboot's verstage as a userspace application to run on the PSP. It does a minimal setup of hardware, then runs verstage_main. It uses hardware hashing to increase the speed and will directly reboot into recovery mode if there are any failures.

2020-06-13	soc/amd/picasso: Place early stages and data buffers at the bottom of DRAM	Furquan Shaikh
	This change updates memlayout.ld for Picasso to place all early stages (bootblock, romstage, FSP-M, verstage) and data buffers (vboot workbuf, APOB, preram-cbmem console, timestamp, early BSP stack) at the bottom of DRAM starting at 32MiB. This uses static allocation for most components by defining Kconfig variables for base and size. It relies on the linker to complain if any of the assumptions are broken. This also allows romstage to use linker symbols for _early_reserved_dram and _eearly_reserved_dram to store information in CBMEM about the early DRAM usage by coreboot before ramstage starts execution. This allows ramstage to reserve this memory region in BIOS tables so that S3 resume can reuse the same space without corrupting OS memory.

2020-06-13	soc/amd/picasso: Add custom memlayout.ld file	Furquan Shaikh
	This change copies src/arch/x86/memlayout.ld file to src/soc/amd/picasso/ and sets MEMLAYOUT_LD_FILE config variable to point to this newly added file. Unused elements from the memlayout.ld file are dropped and path to early_dram.ld is updated to include the one from src/arch/x86.
