[U-Boot] [U-Boot, v2, 19/19] rockchip: Add support for chromebook_bob

[Philipp Tomsich]

> 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.
