arm7_9_restore_context() function

Restore the processor context on an ARM7/9 target. The full processor context is analyzed to see if any of the registers are dirty on this end, but have a valid new value. If this is the case, the processor is changed to the appropriate mode and the new register values are written out to the processor. If there happens to be a dirty register with an invalid value, an error will be logged.

Syntax

static int arm7_9_restore_context(struct target *target);

Arguments

target

Pointer to the ARM7/9 target to have its context restored

Return value

Error status if the target is not halted or the core mode in the armv4_5 struct is invalid.
