Um... on your photo I can clearly read a  "MDPPRA-0207"  tag.  Search
for   terms   like   "MDPPRA-ALL-X  modular  development  board"  and
"ICM86B-860-X MPC860T CPU module".

The MPC860 is the vary starting point of this whoile project. It  was
my  development platform when I started working on a boot loader, and
MPC8xx was the single target we had in mind in all the initial steps.
Only some time later we decided to call this  project  PPCBoot,  long
long before it was renamed into U-Boot.

The fact that you don't see 8xx related patches any more  lately  has
two  reasons:  1) the processor family is more or less obsolete and I
haven't seen it used in any new design for a long, long time (but  it
is  still used in many, many projects, some of them selling in really
high volume). 2) as it was the  reference  platform  right  from  the
beginning,  it  is still one of the best supported architectures, and
the code for it can be consered more or less BugFree (TM) :-)


Best regards,

Wolfgang Denk

Alan Turing thought about criteria to settle the question of  whether
machines  can think, a question of which we now know that it is about
as relevant as the question of whether submarines can swim.
