- * We have the following to choose from:
- * arm6 - ARM6 style
- * 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
- * v5tej_early - ARMv5 with Thumb and Java early abort handler
- * xscale - ARMv5 with Thumb with Xscale extensions
