The tabstop is 8 char, when I use vi to edit the file, it is aligned. 
But when use git send patch, it display like this.
May I need to fix this issue?

sam9x5 is a series SoC (9G15, 9G25, 9G35, 9X25, 9X35) with different 
peripherals. Try to use one configuration file, so it need to decide 
whether SoC supports?
