mapped helpful functions requiring libgcc.a

I've just noticed that the 'mapped' helper function write_flash(), when
compiled with 2.3.17, requires __divdi3 and __moddi3 from libgcc.a
This is because of these two lines (just after line 500, at the beginning of
// Compute the page offset and reposition
base = map->page(map,start/map->pagesize);
off = start % map->pagesize;
Given that our map window is always going to be a power of two, I suggest that
we ought to use shifts instead of div/mod here, and change mapsize to be a
logarithm instead of the actual size.
