29 * Data Abort Model
30 * ================
31 *
32 * We have the following to choose from:
33 * arm6 - ARM6 style
34 * arm7 - ARM7 style
35 * v4_early - ARMv4 without Thumb early abort handler
36 * v4t_late - ARMv4 with Thumb late abort handler
37 * v4t_early - ARMv4 with Thumb early abort handler
38 * v5tej_early - ARMv5 with Thumb and Java early abort handler
39 * xscale - ARMv5 with Thumb with Xscale extensions
40 * v6_early - ARMv6 generic early abort handler
