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

So far we have imx_gpio_mode() to configure a pinmux entry for the older
i.MX pinmuxes. For this to work imx_iomuxv1_init() must be called
beforehand to configure the base address. Simplify this by introducing
SoC specific variants of imx_gpio_mode() which also pass the base
address. This makes initialization of the base address unnecessary and
the functions usable for PBL. Consequently also compile the code for
PBL.
