This makes vboot functional without needing MOCK_TPM and results in the following in the SSDT: Device (TPMI) { Name (_HID, "GOOG0005") // _HID: Hardware ID Name (_UID, Zero) // _UID: Unique ID Name (_DDN, "I2C TPM") // _DDN: DOS Device Name Method (_STA, 0, NotSerialized) // _STA: Status { Return (0x0F) } Name (_CRS, ResourceTemplate () // _CRS: Current Resource Settings { I2cSerialBus (0x0050, ControllerInitiated, 0x00061A80, AddressingMode7Bit, "\\_SB.PCI0.I2C2", 0x00, ResourceConsumer) Interrupt (ResourceConsumer, Edge, ActiveLow, Exclusive) { 0x00000039 } }) } Change-Id: Ia9775caabeac3e6a3bd72de38f9611b4cea7cea4 Signed-off-by: Duncan Laurie Reviewed-on: https://review.coreboot.org/16398 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin --- src/mainboard/google/reef/Kconfig | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-) (limited to 'src/mainboard/google/reef/Kconfig') diff --git a/src/mainboard/google/reef/Kconfig b/src/mainboard/google/reef/Kconfig index 6ef45ccde6..3da0d8b63f 100644 --- a/src/mainboard/google/reef/Kconfig +++ b/src/mainboard/google/reef/Kconfig @@ -7,8 +7,10 @@ config BOARD_GOOGLE_BASEBOARD_REEF select EC_GOOGLE_CHROMEEC_LPC select HAVE_ACPI_RESUME select HAVE_ACPI_TABLES + select I2C_TPM select MAINBOARD_HAS_CHROMEOS - select MAINBOARD_HAS_LPC_TPM + select MAINBOARD_HAS_TPM2 + select TPM2 if BOARD_GOOGLE_BASEBOARD_REEF @@ -16,6 +18,12 @@ config BASEBOARD_REEF_LAPTOP def_bool n select SYSTEM_TYPE_LAPTOP +config DRIVER_TPM_I2C_BUS + hex "0x2" + +config DRIVER_TPM_I2C_ADDR + hex "0x50" + config CHROMEOS select LID_SWITCH if BASEBOARD_REEF_LAPTOP -- cgit v1.2.3
