[U-Boot] [PATCH] rockchip: rk3399: Add Khadas Edge board support

[Chris Webb]

Hi Nick. I think Kever has merged the LPDDR4 series, and it's already made  
its way into the mainline u-boot master branch.

   https://gitlab.denx.de/u-boot/u-boot/commit/852f6ddd76fad2d5adef3f7e3a75d0065c68db3b

and its ancestors are the v3 series Jagan posted to the list.

There have also been a number of other rk3399 cleanups since then, so the  
defconfig might need updating to suit. (I just copied the rock-pi-4  
defconfig and replaced the default device tree.)

Best wishes,

Chris.
