v2021.01.0

[Sascha Hauer]

Hi All,

The first release for the new year is out: barebox-2021.01.0

This release brings us support for the qemu virt platform on ARM, thanks
Rouven. Furthermore there are several fixes for the updated NAND layer,
among other things different ECC modes and write support are now optional
again, so that the produced binaries are small enough again to compile
NAND boot for AM335x platforms. Ahmad has improved Raspberry Pi support
a bit: The RPi zero now has the UART support straight, so output should
appear on the right port. Apart from that there are several more fixes
and small improvements, see below.

Have Fun!
  Sascha
