* ARMv7M: Improve exception handler routine and add comments on SP selectionMartin Galvan2015-09-231-11/+21
| | | | | | | | | This patch adds a brief description of how context state is saved into the SP on exception entry, and makes a few changes to _ARMV7M_Exception_default in order to make it a bit more efficient. I also removed the unused 'v7mfsz' input parameter. This should apply over Sudarshan's patch.
