I am becoming increasingly concerned about the quality, or lack of it, of the 4xx code generally. I think we need someone who has a good amount of experience in Linux kernel coding to go through all the 4xx code and clean it up and simplify it where possible. I know that the 4xx family have quirks (e.g. DCRs) which make it difficult in places to do things simply, but with a bit of creativity we can make the code clearer and simpler than it is at the moment.
I should note that I mostly care about cleaning up the 4xx support in 2.5.x. I don't want to make any major changes in linuxppc_2_4_devel at this stage. At the moment it seems that Tom Rini is the maintainer and Armin Kuster and David Gibson are both working in the area, particularly on the OCP support. It seems though that Tom's life is very busy at the moment with various things. So I am proposing that I will take over the 4xx maintainership for 2.5.x, at least for now, unless someone else with a reasonable amount of kernel hacking cred steps forward and volunteers to do it instead.
