Subject: [PATCH 0/4] i.MX1/scb9328 patches
Date: Wed, 14 Aug 2019 10:16:55 +0200	[thread overview]
Message-ID: <20190814081659.22670-1-s.hauer@pengutronix.de> (raw)

We are currently celebrating 15 years of i.MX support in mainline Linux:

https://git.kernel.org/pub/scm/linux/kernel/git/tglx/history.git/commit/?id=9c496bde802b19db40325bbde356be62e66dc125

For this I took some time to update the i.MX1 based Synertronix scb9328
board support. With the switch to device tree support the board is able
to boot up a recent barebox and a current mainline Linux, see here:

https://asciinema.org/a/VPg3yPZBZfhhqMVN61fAX38Cm

The board only has 16MiB of SDRAM which is very tight nowadays.
For successful boot I have some additional hack in my tree which
arranges the Kernel and device tree in memory in a way that the
device tree won't get overwritten during decompression of the Kernel.
Also I wasn't able to start my systemd based rootfs, probably due
to memory constraints. With init=/bin/sh it works though, but hey,
it's a more than 15 years old hardware ;)

Have Fun!
  Sascha
