each region can have 4 different access states: read/write, read-only,
write-only (never seen in practice), locked (neither read nor write
allowed) (see FREG in the public datasheets for any newer intel
flashrom disables writes by default if it detects locked or read-only
regions as a safety measurement and still allows reads because they can
not lead to the same severe damage. in case of locked regions reads of
addresses inside those regions will of course fail.
there are some patches available that are not merged yet that allow to
specify the addresses to be read/written, which allow to read/write the
readable/writable address ranges.
Kind regards/Mit freundlichen Grüßen, Stefan Tauner
