It's interesting as I'm looking at this further. Sure enough it looks to me like any early mappings in the MMU get destroyed. Paging_init calls devicemaps_init which says it destroys the early debug mappings. Maybe I'm misinterpreting that?
I don't think so. Normally, platforms end up mapping it as part of a larger mappign. If you don't have that then it'll be necessary.
