[PATCH] m68knommu: remove fixed ROM region setups from linker script
Remove the hard coded ROM region setups. Use Kconfig options to specify
these in a generic way for platorms that want them.
This builds on top of the other recent m68knommu linker script changes
to completely remove fixed board configurations.
