The serial bootloader I've used (which comes installed in Wytec's
boards) which came from Freescale Semiconductor loads just fine into the entire
Flash memory as long as the files are in S29 format.
And there is always using the BDM interface, which will eliminate the need for
the bootloader.

via the Serial Bootloader which resides at $F000 in page $3F of the Flash
memory, a protected area. My app starts loading in the programming window at
$C000 in page $3F but cannot go beyond $F000. This limits program size to less
than 12K bytes, a severe limitation when 512K bytes of Flash are available. The
load and erase routines of the Serial Bootloader all reside in $F000 and it can
load apps into the same $3F page, so why can't the Serial Bootloader load
into other pages of Flash like $20?
