Missing spaces before '{'. I was correcting this already:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=66b14154e278807811d67de9fb0d5cc76638d07b
so it seems I need to keep doing the same.

Anyway, the names should follow purpose, not "memory". See link from Konrad.


Best regards,
Krzysztof

Yes, mea culpa. Please excuse me for the suggestion, I was looking at
the older device tree files.
