If the Top Swap mechanism is enabled, after running the bootblock from the TOP_SWAP region, boot from an updatable COREBOOT_TS FMAP region. Having flashed the TOP_SWAP bootblock and COREBOOT_TS, this allows the user to boot a newer version of the firmware with the ability to revert to the previous known-good version by performing a CMOS reset. Requires having a read-write COREBOOT_TS region in the FMAP file. This is part of an ongoing implementation of a redundancy feature proposed on the mailing list: https://mail.coreboot.org/archives/list/coreboot@coreboot.org/thread/C6JN2PB7K7D67EG7OIKB6BBERZU5YV35/ TEST=Boot Protectli VP6650, setting the attempt_slot_b flag to different values, observing the "Booting from COREBOOT/COREBOOT_TS region" prints correspondingly.
