U-Boot, video console, and visual artifacts

I agree that it looks like the framebuffer is overwritten and filled with garbage, but I think that's just one part of the mix that causes this issue.

In one of the attempts to fix this issue, I've modified the U-Boot drivers for the RK3399 eDP output and the RK3399 VOP to get removed and turn the hardware off before booting into the Linux kernel, which made the "second plaid" (the one when the kernel starts) pattern to disappear, but also caused my PineBook Pro to lock up while attempting to boot the kernel.  I still need to debug that.
