If you can execute some code from FLASH then you don't seem to have a problem 
with the I2C bootstrap configuration after all. Your U-Boot port is just not 
correct and crashing/hanging at some time.

No. Most likely you need to configure the some PCI related registers in the 
440GX core so that it can be accessed via the PCI bus (BAR address mapping 
etc).

As it seems this is not a problem with the bootstrap controller. But I still 
recommend that you download the manuals from the Applied Micro (AMCC) page 
yourself.
