2020-09-14soc/amd/picasso: copy local info to transfer bufKangheui 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. BUG=b:159220781 BRANCH=zork TEST=check transfer_info_struct is correctly populated on romstage Signed-off-by: Kangheui Won <khwon@chromium.org> Change-Id: I14bc34e6af501240a6f633db3999a7759e88d60b Reviewed-on: https://review.coreboot.org/c/coreboot/+/44751 Reviewed-by: Martin Roth <martinroth@google.com> Reviewed-by: Edward O'Callaghan <quasisec@chromium.org> Reviewed-by: Aaron Durbin <adurbin@chromium.org> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>

Add vb2ex_hwcrypto_rsa_verify_digest function for verifying rsa signature against digest using PSP svc. This function will be later used by vboot to accelerate rsa verification. BUG=b:163710320, b:161205813 TEST=build zork firmware with vboot modification, confirm it's booting and boot time is reduced by ~230ms.

2020-08-24soc/amd/picasso: Reboot for recovery if no psp workbuf is foundMartin 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.
