Sure.  So why don't you:
1. Turn physmap.c into a platform driver.
2. Rename physmap.c into something.c
3. Remove unnecessary generic code from something.c
4. Submit a patch adding something.c

Instead, steps 2 and 3 were skipped and physmap itself was supposed to
become a platform driver.  And at the moment I don't understand the
advantages of skipping said steps.
