2017-04-24google/oak: Support cr50 over I2C on rowanVadim Bendebury
This patch enables TPM2 using cr50 over I2C for the Rowan board, and adds an mt8173 specific TPM IRQ polling function. The function relies on the appropriate EINT input configured to trigger the ready status on the rising edge. The cr50 TPM is on I2C address 0x50. The cr50 interrupt GPIO is also made available for use by depthcharge via the coreboot tables. BRANCH=none BUG=b:36786804 TEST=Boot rowan w/ serial enabled, verify coreboot and depthcharge are configured to use IRQ flow control when talking to the Cr50 TPM.

2016-05-09google/oak: Add derivative board ElmJulius Werner
This patch adds a new mainboard Google/Elm as a derivative of Google/Oak, using the same code sharing technique for derivative boards that was pioneered with Google/Veyron*. For now, there are no firmware-relevant fundamental differences between the two boards. In addition, introduce a board-specific Kconfig for the "board ID adjustment" to represent the fact that the Elm board ID space mirrors the Oak board ID space with an offset of 6, meaning Elm rev0 is equivalent to Oak rev6, and future board changes will be made on both boards to maintain this stride (at least virtually... not all of those revisions will necessarily get built). This should make it much easier to keep the code that handles revision differences somewhat clean. (That's the theory, anyway... whether it will work out remains to be seen.) BRANCH=None BUG=None TEST=Booted Elm image with hardcoded board ID 0 on Oak rev6.
