* 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
