Basically, 1st you need to understand how your arch (in this case ARM) works during boot stage. let's say it's doing interrupt table initialization. Using this clue, use grep to find any words related to "interrupt" inside arch/arm directory. Maybe you don't jump right into the very beginning phase of booting, but by doing backtracking (find out which code calling this spot), eventually you can find it out. Cscope/ctag is your best friend for this of work. regards, Mulyadi. -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
