For Kerenl porting/u-boot porting there are 3 types of files added/changed

1.cpu spefic files  [arm cortex-A8 processor]
2.Machine/architecture spefic files [AM335x ]
3.Board spefic files [Beagle bone]

Machine/Architecture spefic files are presented commonly in cpu and 
board realted files for ex.arch/arm/cpu/armv7/am335x/*.c 
[for armv7 processor --are cortex A8 and for am335x architecture spefic]

Complete analysis of template board file, this file gives minium requirements 
for the board to up and it gives priority to user to add other I/O devices such
as LCD, MMC, NAND for providing kerenl support.
