MTD, generic physmap memory, MTD_BLOCK

[David Woodhouse]

Unless there's something missing (or I'm being dim) that code doesn't do
XIP. It still copies from the cramfs into the page provided to
cramfs_readpage.

What you want to do is make up some struct pages to represent the pages
of the ROM chip and pre-populate the page cache with those pages directly
- marked readonly, of course.
