How about using some existing firmware?

Don't re-invent  the  wheel  again  and  again.  All  this  has  been
implemented  so  many  times  before.  Grab  for instance the PPCBoot
sources, and use these.

Or even better,  check  if  PPCBoot  does  not  provide  exactly  the
functions  you are trying to implement yourslef (and if it doesn't it
may still be simpler to contribute your extensions to PPCBoot instead
of starting from scratch).
