Sorry, but no. This is off topic on this list.

U-Boot is a boot loader, i. e. low level software that requires an intimate knowhow about the hardware and at least the ability to read and understand assembler and C code.

Please check the Manual (especially
http://www.denx.de/twiki/bin/view/DULG/MoreInformationBooks) for more information about PPC programming.
