/*
 *	Data Abort Model
 *	================
 *
 *	We have the following to choose from:
 *	  arm7		- ARM7 style
 *	  v4_early	- ARMv4 without Thumb early abort handler
 *	  v4t_late	- ARMv4 with Thumb late abort handler
 *	  v4t_early	- ARMv4 with Thumb early abort handler
 *	  v5t_early	- ARMv5 with Thumb early abort handler
 *	  v5tj_early	- ARMv5 with Thumb and Java early abort handler
 *	  xscale	- ARMv5 with Thumb with Xscale extensions
 *	  v6_early	- ARMv6 generic early abort handler
 *	  v7_early	- ARMv7 generic early abort handler
