2021-01-28	soc/amd/picasso: fix CBFS MCACHE on Zork	Kangheui Won
	Zork platform was not booting with MCACHE enabled since psp_verstage had following issues with MCACHE. Fix all the issues and re-enable MCACHE for Zork. * psp_verstage should call vboot_run_logic, not verstage_main. vboot_run_logic calls after_verstage which handles RW MCACHE build. * It should avoid low-level apis for cbfs access. cbfs_map will build RO MCACHE if it's the first stage, while other low-level apis won't. * It should call update_boot_region before save_buffers MCACHE should be transferred to x86 so we should build it before calling save_buffers BUG=b:177323348 BRANCH=none TEST=boot Ezkinil Signed-off-by: Kangheui Won <khwon@chromium.org> Change-Id: I08c5f8474600a06e3a08358733a38f70787e944a Reviewed-on: https://review.coreboot.org/c/coreboot/+/49468 Reviewed-by: Raul Rangel <rrangel@chromium.org> Reviewed-by: Julius Werner <jwerner@chromium.org> Reviewed-by: Marshall Dawson <marshalldawson3rd@gmail.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
2020-12-09	soc/amd: factor out legacy I/O and cf9 decode enable functions	Felix Held
	Replace sb prefix with fch prefix, since those are all FCHs and no south bridges any more. Verstage on PSP uses the I/O access mechanism instead of the MMIO one, so keep a separate function for that, but also move it to the common mmio_util file to have them all in one place.

2020-09-22	soc/amd/picasso: record timestamps in psp_verstage	Kangheui Won
	Verstage in PSP used stub for timestamps since we didn't know about clock. Now we figured out clock source so we can enable timestamp functions.

2020-09-14	soc/amd/picasso: copy local info to transfer buf	Kangheui Won
	We added transfer_info_struct to contain various information about memory region we pass from PSP to x86 in commit 0c12abe462. This should be at the start of transfer region but we only manipulated it as local variable and didn't put data into the region, resulting garbage data for transfer_info when x86 tries to read it. Copy the content of local variable to beginning of _transfer_buffer before requesting transfer to PSP so coreboot on x86 can access it.

2020-08-25	soc/amd/picasso: If psp_verstage is in RO, don't reset on error	Martin Roth
	If there's already been an error and PSP_verstage is booting to RO, don't reset the system. It may be that the error is fatal, but if the system is stuck, don't intentionally force it into a reboot loop.

2020-08-24	soc/amd/picasso: Reboot for recovery if no psp workbuf is found	Martin Roth
	Instead of halting if the vboot workbuf is not passed to coreboot by the PSP, reset and reboot into recovery mode. This process is made more difficult because if the workbuf isn't available, we can't reboot directly into recovery - the workbuf is needed for that process to be done through the regular calls, and we don't want to go around the vboot API and just write into VBNV directly. To overcome this, we set a CMOS flag, and reset the system. PSP_verstage checks for this flag so it will update VBNV and reset the system after generating the workbuf. BUG=b:152638343 TEST=Simulate the workbuf not being present and verify the reboot process.

	Switch from locating the AMD firmware in the RW_A & RW_B regions with their hardcoded locations to using CBFS to find them. They still need to be at the hardcoded locations so that we can set the location inside the binary, but instead of just setting the pointer directly to them, we now search for them with cbfs.

	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.
