State-Changed-From-To: open->closed
State-Changed-Why: Given the potential for this to be in other BSPs, I wanted

to take the time to review all BSPs. All other BSPs appeared
to do this correctly. They either did the math on
unsigned32's, void *, or char *. I did modify the
other SH BSPs because they were doing the math on
integer pointers and multiplying by the size of
an unsigned32. Since this was inconsistent with
other BSPs (although 100% correct) I changed it.

Thanks for spotting and reporting this.
