Switch SST49LF004A/B to block erase, remove the hack which simulated (unsupported) chip erase
Annotate SST49LF004B quirks for TBL#. Add TEST_OK_PRW which is useful when a
PREW chip gets a new erase routine. Change a few erase function prototypes
to use unsigned int instead of int.
Corresponding to flashrom svn r731.
