v2021.04.0

[Sascha Hauer]

Hi All,

barebox-2021.04.0 is out.

This release brings us nice improvements for the RISC-V architecture.
barebox for RISC-V now has full PBL support and builds a generic 2nd
state dt image to be used with Qemus virt machine.  See
Documentation/boards/riscv.rst, it's worth checking out.

The second great feature this time is cooperative multitasking support.
It is implemented using setjmp/longjmp and is available on all supported
architectures. Multitasking is currently unused unless explicitly
enabled in Kconfig. When enabled all that's currently available is a
test command, but in future pollers can be implemented using threads and
porting over kernel code could become simpler.

As usual, see the full list of changes below. Thank you all for
participating!

Have Fun!
  Sascha
