| * | Fix return address when data_abort_handler skips faulting instruction. | Boris Gjenero | 2013-05-23 |
| | | | | | | | | | | When writing a value to PC, execution continues at that location, so subtracting 4 returns to the next instruction. Previously, two instructions after the faulting instruction were being skipped, causing safe_read functions to return true even if a data abort happened.

| * | arm: implement safe reads by intercepting the data abort handler. | Amaury Pouly | 2012-04-06 |
| Implement functions to read from a memory location and indicate failure in case this is not possible. Since we do not have a MMU, intercept the data abort handler and simply return when the abort comes from the safe read routines.
