[U-Boot-Users] U-Boot with gcc-3.3.2 and ARM926EJS Targets fails due to __udi

There is a full set already available in the gcc? But anyway, it makes not 
much sense using two different gcc compilers. One for the bootloader, one for 
applications. And with which one has the linux kernel to be compiled?

Yes, of course. Now I see it. I'm needing the non-power 2 division only in the 
serial driver for calculation the baudrate divisior. And libdrivers has been 
after libarm :-(

Thank you, it works fine. Therefore, in the near future a new board and CPU 
will be supported by U-Boot :-)

Bye,
