It's been broken almost 15 months since the commit below:
"commit aa91796ec46339f2ed53da311bd3ea77a3e4dfe1
Author: Christophe Leroy <christophe.leroy@c-s.fr>
Date: Tue Oct 9 13:51:41 2018 +0000
powerpc: don't use ioremap_prot() nor __ioremap() unless really needed."
And we are working on it now for further development.
