Hello;
While working on i2c support, I've decided to update to a new kernel. In
the process of doing this, I'm not sure I've properly configured the MURAM
node to my device tree (i.e. serial is broken again). Also, does this, in
any way, change the way I offset the early debug transmit descriptor
address?
I tried looking at your cpm tree on git.buserror.net, but it seems you've
taken it down?

You haven't -- you copied muram/data/reg from some other tree, rather
than from resource 2 of cpm/reg in your old tree.

No.

muram/data/reg should be <80 1f80 9800 800> for your board.
