google/reef: Enable I2C TPM
Enable the I2C based TPM on the reef board at
bus 2 and address 0x50.
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
}
})
}
