The configuration file says that the kernel should start at 0x00080000, and there's no way the .text VMA should be starting at 0x3f0801a0. Unless one of the XIP using folk can debug this, I doubt there will be any movement on it. Especially as it's 5 months old... What do we do with bugs like this that people won't fix? Remove XIP support from the kernel?
