https://ticket.coreboot.org/issues/457#change-1402 test with libre mrc, fiddle to see if can get s3 resume working s3 resume works on libre mrc or can work, code is there in the native src for mrc that hell wrote also: -b switch in cbfstool, value: 0x78fe00 minus 0x40 of that becomes the offset in cbfstool print for mrc.bin. i fixed that issue last night with blobtool insert, but i need to know if the offset above is always that number, or if it changes depending on some circumstance, and if so, how i need to calculate (last paragraph referring to blobtool insert bug for 20230319) this issue report doesn't make sense because it's for me. it's a todo note tlaurion i'll get back to you on irc when i tested it
