See my comments elsewhere about why this is Really Bad.  Any casts outside of a few header files using __force are basically a bug.

In this case, you're being forced to use them because OMAP2_IO_ADDRESS doesn't return the proper pointer values.  (I produced a patch for comment on this list last week over this issue.)

[sp] I was trying to be consistent/similar with current code in the file. Will make appropriate changes as you suggest.
