Subject: [PATCH] soc/intel/lockdown: Allow locking down SPI and LPC in SMM
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Heads payload uses APM_CNT_FINALIZE SMI to set and lock down
the SPI controller with PR0 flash protection. Add new option
to skip LPC and FAST SPI lock down in coreboot and move it
to APM_CNT_FINALIZE SMI handler.
Heads payload uses APM_CNT_FINALIZE SMI to set and lock down the SPI
controller with PR0 flash protection for pre-Skylake platforms.
Add new option to skip LPC and FAST SPI lock down in coreboot and move
it to APM_CNT_FINALIZE SMI handler. Reuse the INTEL_CHIPSET_LOCKDOWN
option to prevent issuing APM_CNT_FINALIZE SMI on normal boot path,
like it was done on pre-Skylake platforms. As the locking on modern
SOCs became more complicated, separate the SPI and LPC locking into
new modules to make linking to SMM easier.
The expected configuration to leverage the feautre is to unselect
INTEL_CHIPSET_LOCKDOWN and select SOC_INTEL_COMMON_SPI_LOCKDOWN_SMM.
Testing various microarchitectures happens on heads repository:
https://github.com/linuxboot/heads/pull/1818
TEST=Lock the SPI flash using APM_CNT_FINALIZE in heads on Alder Lake
(Protectli VP66xx) and Comet Lake (Protectli VP46xx) platforms. Check
if flash is unlocked in the heads recovery console. Check if flash is
locked in the kexec'ed OS.
