This is the initial addition of the port of RTEMS to the
Hitachi H8 family. This port was done by Philip Quaife
<philip@…> of Q Solutions and sponsored by
Comnet Technologies Ltd. The port was done based on RTEMS 3.5.1
to a Hitach H8300H. The port was updated to RTEMS 4.5 style
Makefiles/configure by Joel Sherrill <joel@…>.
While doing this Joel added support for the h8300-rtems to
binutils, gcc, newlib, and gdb.

NOTE: Philip submitted a BSP for a Hitachi evaluation board
which is being merged as a separate entity.
