soc/amd/picasso: copy local info to transfer buf
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>
