vc/amd/fsp/picasso: Add AMD code to support psp_verstage
Add the AMD supplied code (modified to work with GCC) to the vendorcode directory. Verstage will be running on the PSP as a userspace application under the bootloader, which is what bl_uapp signifies. AMD is still working on documentation for the entire PSP userspace application interface. BUG=b:158124527 TEST=Build & boot psp_verstage on Trembyle Signed-off-by: Martin Roth <martin@coreboot.org> Change-Id: Ie740c89afe2277eff279fc5c94f88ffd43a78a37 Reviewed-on: https://review.coreboot.org/c/coreboot/+/42060 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Raul Rangel <rrangel@chromium.org>
