Hi Gerald,

   The attached patch updates the gcc html documentation to mention the 
new RX command line option that I checked in today.  Is this patch OK to 
apply ?

Cheers
   Nick

This looks good to me, thank you!

The only question I have is: where it says "on addresses with 
the I/O space of the processor", might that be "within"?
