From: Daniel Henrique Barboza <[email protected]>
The mcontrol select bit (19) is always zero, meaning our triggers will
always match virtual addresses. In this condition, if the user does not
specify a size for the trigger, the access size defaults to XLEN.
At this moment we're using def_size = 8 regardless of CPU XLEN. Use
def_size = 4 in case we're running 32 bits.
