Thanks for the advice, but for some reason, both (CW and DW) version did'nt 
work on their own.  I had to use the RPXlite config and settings, but with 
the flash.c from the RPXlite_DW.  There must be something else I have to do 
because I cannot write on the flash.  The "saveenv" command does'nt work.

I know it is weird, but when I was using the RPXlite_DW config, U-boot could 
not start.  When I used RPXlite, I started, but got stuck on the flash memory 
detection and I had a little warning saying that the processor is not the 
same as specified.  That's why I changed it by replacing
#define CONFIG_MPC850
by
#define CONFIG_MPC823
in the RPXlite.h file, but I'm still having a warning.

So, to conclude, can someone help me about the flash memory problem.  I would 
really like to understand this problem.  Also, if someone knows the right 
settings to "remove" the processor warning, I'm all ears.

My flash memory is mapped from 
FF00 0000
to 
FFFF FFFF
and u-boot has to be put at FFF0 0000 to boot
