Add Kconfig INTEL_TOP_SWAP_SEPARATE_REGIONS. When enabled, place the regular bootblock in BOOTBLOCK and the Top Swap bootblock in TOPSWAP to simplify A B updates. This lays groundwork for redundancy where one bootblock remains a read only golden copy and the other is replaceable. No swap control logic is added in this change. The option depends on INTEL_ADD_TOP_SWAP_BOOTBLOCK and defaults to n so existing builds are unchanged. A custom .fmd is required with BOOTBLOCK and TOPSWAP added at the end of the image. Background and update flow are described here: Link: https://mail.coreboot.org/archives/list/coreboot@coreboot.org/thread/C6JN2PB7K7D67EG7OIKB6BBERZU5Y V35/ TEST=Build and run Protectli VP6650 (ADL-P), boots successfully with correct microcode Change-Id: I489406dd8d08ad85bb46324d3d009acb49b6c52a Signed-off-by: Filip Lewiński <filip.lewinski@3mdeb.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/89570 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Sergii Dmytruk <sergii.dmytruk@3mdeb.com> |
