Log Message
set phys to NO_XIP so that highler layers do not attempt to use point() on us (which is basically mmap() for mtd devices) ... our mapping driver needs to be consulted on every access since the addressing goes through gpios
future work may involve us implementing our own point() function so that we can at least support subwindows ...
