[split] U-Boot with NVMe support, keyboard & display working

[Arwen]

@FeMike, First, try learning more about your existing system. Dealing with U-Boot is very experimental, and has the potential to soft-brick your Pinebook Pro.

If you are really new to Linux, you need to check the kernel level with the following command. Then you can see if your kernel is at 5.9.2 or higher.

Code:

uname -r

I've been working with Unix for more than 25 years, and still get bit by odd things. It's never fun to spend hours trying to recover from some bonehead mistake, That of course you did not know was a bonehead mistake, until after.
