Subject: [PATCH] soc/intel/lockdown: Allow locking down SPI and LPC in SMM

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.
