On those systems we need to wait for a bit before executing the VBIOS. config RESET_ON_INVALID_RAMSTAGE_CACHE bool "Reset the system on S3 wake when ramstage cache invalid." default n depends on RELOCATABLE_RAMSTAGE help The romstage code caches the loaded ramstage program in SMM space. On S3 wake the romstage will copy over a fresh ramstage that was cached in the SMM space. This option determines the action to take when the ramstage cache is invalid. If selected the system will reset otherwise the ramstage will be reloaded from cbfs. config MONOTONIC_TIMER_MSR def_bool y select HAVE_MONOTONIC_TIMER help Provide a monotonic timer using the 24MHz MSR counter. config INTEL_PCH_UART_CONSOLE bool "Use Serial IO UART for console" default n select HAVE_UART_MEMORY_MAPPED select CONSOLE_SERIAL8250MEM depends on !CONFIG_DRIVERS_OXFORD_OXPCIE config INTEL_PCH_UART_CONSOLE_NUMBER hex "Serial IO UART number to use for console" default "0x0" depends on INTEL_PCH_UART_CONSOLE config TTYS0_BASE hex default 0xd6000000 depends on INTEL_PCH_UART_CONSOLE config EHCI_BAR hex default 0xd8000000 config EHCI_DEBUG_OFFSET hex default 0xa0 config SERIRQ_CONTINUOUS_MODE bool default y help If you set this option to y, the serial IRQ machine will be operated in continuous mode. config ME_MBP_CLEAR_LATE bool "Defer wait for ME MBP Cleared" default y help If you set this option to y, the Management Engine driver will defer waiting for the MBP Cleared indicator until the finalize step. This can speed up boot time if the ME takes a long time to indicate this status. config LOCK_MANAGEMENT_ENGINE bool "Lock Management Engine section" default n help The Intel Management Engine supports preventing write accesses from the host to the Management Engine section in the firmware descriptor. If the ME section is locked, it can only be overwritten with an external SPI flash programmer. You will want this if you want to increase security of your ROM image once you are sure that the ME firmware is no longer going to change. If unsure, say N. endif
