17  *	We have the following to choose from:
18  *	  arm7		- ARM7 style
19  *	  v4_early	- ARMv4 without Thumb early abort handler
20  *	  v4t_late	- ARMv4 with Thumb late abort handler
21  *	  v4t_early	- ARMv4 with Thumb early abort handler
22  *	  v5t_early	- ARMv5 with Thumb early abort handler
23  *	  v5tj_early	- ARMv5 with Thumb and Java early abort handler
24  *	  xscale	- ARMv5 with Thumb with Xscale extensions
25  *	  v6_early	- ARMv6 generic early abort handler
