hi to all 

I'm trying to port bootldr to a new PXA255 board, probably I'll ask
something of well know but I don't find answer to my questions.

- where I can find documentation about bootldr or in general what a 
bootldr do.

- a list of what architectures (various ipaq mainly) bootldr support and
(brief) description of such hardware so can be more simple to understand
the config structure of bootldr.

I have download via CVS the latest bootldr,

- at now bootldr seem to run on the new board, and as first thing i
would be able to make splash screen visible. I have change the LCCRx
registers setup in lcd_color_params in th lcd-pxa.c file but nothing
happen :( ... what I miss ??? 

- how I can make test without every time burn bootldr in flash, how I
can use bootldr-c340 that I understand should run in memory ??? 

I try to load it at 0xA3400000 memory address but nothing (of good)
happen, that's the dump ...
