Apollo Lake is an Intel SoC generation aimed at relatively low-end embedded systems. It was released in 2016 but has become more popular recently with some embedded boards using it.
This series adds support for Apollo Lake. As an example it adds an implementation of chromebook_coral (a large range of Chromebooks released in 2017).
The series provides enough support to boot to a prompt. with LCD display, storage, USB, EC and keyboard.
Since this is the first time U-Boot has used FSP2 there is quite a bit of refactoring needed.
This series is available at u-boot-dm/coral-working
