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.
