9ed93cb5d5 gru: kevin: configure board GPIOs
Set board GPIOs as required and add their description into the
appropriate section of the coreboot table, to make them available to
depthcharge.

BRANCH=none
BUG=chrome-os-partner:51537
TEST=with the rest of the patches applied it is possible to use
     keyboard on Gru, which indicates that the EC interrupt GPIO is
     properly configured. The rest of the pins will be verified later.

591298a575 google/gru: enable pp1500 and pp3000 rails as soon as possible
The idea is that they stay low unless we know that we booted from SPI
flash. As this code runs in SPI flash - it is ok to turn these rails
on as soon as possible, and pp3000 rail it is essential for UART to
work.

Kevin rev1 and Gru designs are going to be using these pins to
control these rails. Kevin rev1 had those GPIO pins routed to two
chip enable signals, it is save to assert them high.

BRANCH=none
BUG=chrome-os-partner:51537
TEST=kevin rev0 still boots (which does not prove much)
TEST=run coreboot on kevin rev1 to kernel

be929f41af google/gru: select 1.8V as gpio2ab io domain
On kevin board, both the gpio2ab's io domain APIO2_VDDPST and
APIO2_VDD are 1.8V. So gpio2ab can only output 1.8V.

BRANCH=none
BUG=chrome-os-partner:52510
TEST=Apply this patch, CPU1_SDIO_PWREN(GPIO2_A2) can output 1.8V

347c83cfc9 rockchip: rk3399: add spi clock driver
This patch implements spi clock driver and initialize
SPI flash rom for the baseboard gru.

There are 6 on-chip SPI controllers inside RK3399. For
SPI3, it's source clk from ppll, while the others from gpll.

Please refer to CRU session of TRM for detail.

a6dbfb5808 google/gru: Add a stub rk3399 mainboard
Most things still need to be filled in, but this will allow
us to build boards which use this SOC.

[pg: separated out from the combined commit that added both SoC and
board. Added board_info.txt that will be added downstream, too.]
