Shyam Saini shyam.saini at amarulasolutions.com
Thu Apr 18 15:32:05 UTC 2019


This initial support includes:
	Custom u-boot
	Linux v5.1-rc1
	ATF v2.0
	Buildroot default packages

Mainline uboot does not automatically builds so one
u-boot patch is add to fix this

Rk3399 soc based board uses python pyelftools library in uboot so it
is mad as uboot dependency.

This support is added on top of these two patches:
[1] https://patchwork.ozlabs.org/patch/1087590/
[2] https://patchwork.ozlabs.org/patch/1087591/


Here are complete test boots logs for this support:
