v2020.08.0

[Sascha Hauer <s.hauer@pengutronix.de>]

Hi All,

barebox-2020.08.0 is out.

This release has some optimizations in the ramfs implementation. ramfs
now stores the files contiguously in memory which means we can return
a direct pointer to the data in memmap(). With this we potentially need
less copying in memory. Also we need less memory chunks in ramfs, so
performance could slightly increase.

Also we gained support for another i.MX8 SoC variant, this time it's the
i.MX8MP. It's quite similar to other i.MX8 SoCs, so support should be
fairly complete already.

The TLSF allocator is updated to v3.1. This shouldn't change much, but
might be another place to watch out for regressions.

There are many more changes, see below for a full list.

Have Fun!
 Sascha
