My bad. OMAP is doing pretty nasty things with their early serial port support. This is most likely to screw up XIP. > If anyone is using XIP on in-tree platforms, I'd like to hear > about it. > > As for in-tree-ness - I thought the most recent message was to stay > out of tree until the refactoring was over. ;-) Just to be clear... We have XIP in the tree already. If it is useful to someone, in-tree or out-of-tree, then it is worth keeping around. Even if the only user was out-of-tree which certainly wasn't the case when I added XIP support to the kernel, then ripping it out and adding it back later would be more trouble than preserving it. What I was asking recently is whether or not XIP is still useful to someone today. Apparently it is, which is the answer I was looking for.
