* 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
|
|
* v6_early - ARMv6 generic early abort handler
|
|
* v7_early - ARMv7 generic early abort handler
