[PATCH 0/2] Add Block Protect (BP) and Top Bottom (TB) bits for write protect

Posted by Iris Chen 3 years, 7 months ago

Hey everyone,

Adding the 3 block protection bits and top bottom bits which configure which parts
of the flash are writable and read-only.

These patches are based on previous patches I just submitted:
hw: m25p80: fixing individual test failure when tests are running in isolation
hw: m25p80: add WP# pin and SRWD bit for write protection
hw: m25p80: add tests for write protect (WP# and SRWD bit)

The tests that were added iterates through every different memory protection
case so it takes a little longer to run. Let me know what you think about that
and if that's okay or not.

Thanks,
Iris
