Cover letter [U-Boot] [PATCH v3 00/25] dm: Introduce Rockchip RK3288 support
Quoted 10 lines · Simon Glass
The Rockchip RK3288 is based on a quad-core Cortex-A17 CPU and has a good set of peripherals. Various full-featured U-Boot ports are available and this is an attempt to bring those features into mainline. With this series the Firefly RK3288 can boot to a prompt from an SD card.
Since much of the code is generic, this also supports the Radxa Rock Pro. Since there is no device tree available for that yet, it uses the same config and device tree as the Firefly. This works because not all peripherals are supported, so the differences don't matter.

Support for booting from USB OTG is also provided, using the on-chip boot ROM and the rkflashtool utility. This can boot as far as SPL, but there is no support for reading U-Boot proper from USB as yet. This requires implementing a suitable protocol (perhaps DFU or Rockchip's proprietary one) in SPL.
Support is also provided for the Haier Chromebook, which is based on the same SoC. In this case it boots from SPI rather than an SD card.
Any testing on the Hisense Chromebook with the same SoC? I don't know if there are significant differences with the Haier one that would effect this.
