2017-03-23firmware: meson-sm: Check for buffer output sizeCarlo Caione1-2/+2
After the data is read by the secure monitor driver it is being copied in the output buffer checking only the size of the bounce buffer but not the size of the output buffer. Fix this in the secure monitor driver slightly changing the API. Fix also the efuse driver that it is the only driver using this API to not break bisectability.
