Hey everyone, 

My patch adds the W# pin and SRWD bit which work together to control the
status register write ability. 

Accordingly, when W# is low and SRWD bit is high, hardware protection
mode (HPM) is initiated. All other cases result in software protection. 

Acceptance tests have been added to verify all four scenarios: it tests
the ability to write to SRWD depending on whether write protection is
set. 

Thanks, 
Iris
