RPXclassic PPCBOOT on RAM

[Yoo. Jonghoon]

>From my experience, it is required at least 3 things to
be changed If ppcboot works well from flash,
(1) TEXT_BASE to be located in RAM
(2) set CFG_MONITOR_BASE equal to TEXT_BASE
(3) skip DRAM initializaion sequence in func. initdram(),
     except returning size of DRAM.

Good luck to you
