I am just going to answer this question because is the only that I know more . check in google kernel-porting.pdf it is a presentation that tell you how does the embedded developers have to understand x86 kernel in order to pass make it work for ARM architecture, besides the cross compiler for arm architecture the structure of the kernel could be different and yes there is simple structure on the board file where tells you which machine is, and which architecture is. And please do not top post :) Hope it helps Victor Rodriguez > How the process pass the data into the processor and get the output? > Does any relation exists b/w file-system and the page table in hardware > address ? > How the kernel load new memory area from the physical disk to RAM.
