rockchip: Add support for chromebook_bob
Bob is a 10-inch chromebook produced by Asus. It has two USB 3.0 type-C
ports, 4GB of SDRAM, WiFi and a 1280x800 display. It uses its USB ports
for both power and external display. It includes a Chrome OS EC
(Cortex-M3) to provide access to the keyboard and battery functions.
Support so far includes only:
- UART
- SDRAM
- MMC, SD card
- Cros EC (but not keyboard)
Not included:
- Keyboard
- Display
- Sound
- USB
- TPM
Bob is quite similar to Kevin, the Samsung Chromebook Plus, but support
for this is not provided in this series.
