Description

This is needed in order to deal with TrustZone, RYF, mainline Linux, and making it so our current flagship devices can run GNU/Linux distros.

It is my understanding that this currently works, but no u-boot console shows up on the display if you use the old linux kernel from Samsung that we are currently using.

"It's also worth mentioning that LineageOS/Replicant will boot under u-boot with a kernel compiled without CONFIG_ARM_TRUSTZONE set, but the display will not work (probably because u-boot does not initialise the display)."

I just learned from PabloPL on the Replicant IRC that the Exynos 4210 device i9300 can be ported to u-boot as well: https://github.com/xc-racer99/u-boot-galaxys4g/wiki
