Also SmartFirmware hangs up with 2GB memories(1G x2).

Problems:
  1. some pmap and/or pool_cache error happen with SmartFirmware's error
     report.

     Also the BSS section was made dirty by it.  I look, can't attach
     mainbus.  Because the variable 'config_initialized' was changed to
     not 0 by it.

  2. Any process was not able to be executed, because no memory when the
     multiuser mode, in my memory.  It is logged in and will be generated
     in only about one minute...

Sure.  Also edit to my source now.

Yes.  MorphOS 2.3 works.  However, I have seen the strange message output
to the console several times up to now.

I will get some memories. (256Mx2 or 512Mx2).

I merge EV64260's gt(4)(Discovery) to my Marvell Orion(ARM SoC) now.  Next,
merge PegasosII's MV64361 (Discovery II).
