3 config SOC_INTEL_COMMON_BLOCK_SMM
6 Intel Processor common SMM support
8 config SOC_INTEL_COMMON_BLOCK_SMM_IO_TRAP
11 Intel Processor trap flag if it is supported
13 config SOC_INTEL_COMMON_BLOCK_SMM_LOCK_GPIO_PADS
16 Enable locking of security-sensitive SoC and mainboard GPIOs.
17 An SoC may provide a list of gpios to lock, and the mainboard
18 may also provide a list of gpios to lock.
20 config SOC_INTEL_COMMON_BLOCK_SMM_ESPI_DISABLE
24 Disable eSPI SMI source to prevent the embedded controller
25 from asserting SMI while in firmware.
27 config SOC_INTEL_COMMON_BLOCK_SMM_TCO_ENABLE
31 Enable TCO SMI source to e.g. handle case instrusion.
33 config SOC_INTEL_COMMON_BLOCK_SMM_S5_DELAY_MS
35 default 100 if CHROMEOS
38 Time in milliseconds that SLP_SMI for S5 waits for before
39 enabling sleep. This is required to avoid any race between
40 SLP_SMI and PWRBTN SMI.
42 config HECI_DISABLE_USING_SMM
44 depends on SOC_INTEL_COMMON_BLOCK_SMM
47 HECI disable using SMM. Select this option to make HECI disable
48 using SMM mode, independent of dedicated UPD to perform HECI disable.
50 config PERIODIC_SMI_RATE_SELECTION_IN_GEN_PMCON_B
52 depends on SOC_INTEL_COMMON_BLOCK_SMM
55 Intel Core processors select the periodic SMI rate via GEN_PMCON_A.
56 On Intel Atom processors the register is different and they use
57 GEN_PMCON_B/GEN_PMCON2 with different address.
