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 | |
