This is follow up (or fix) for commit 26a1eb514ccefc61b110068cf0eea73c397ba045 When probing opcode, all opcodes in POSSIBLE_OPCODES are reported as supported, even if the opcode is not in curopcodes. This is relying on reprogramming on-the-fly to handle the gap between POSSIBLE_OPCODES and curopcodes. However, for locked chipsets on-the-fly is not happening (is not possible, since list of opcodes is locked), so we can't rely on it. So, we need to check whether chipset is locked.

flashrom README
===============
flashrom is a utility for detecting, reading, writing, verifying and erasing
flash chips. It is often used to flash BIOS/EFI/coreboot/firmware images
in-system using a supported mainboard, but it also supports flashing of network
cards (NICs), SATA controller cards, and other external devices which can
program flash chips.
It supports a wide range of flash chips (most commonly found in SOIC8, DIP8,
SOIC16, WSON8, PLCC32, DIP32, TSOP32, and TSOP40 packages), which use various
protocols such as LPC, FWH, parallel flash, or SPI.
Do not use flashrom on laptops (yet)! The embedded controller (EC) present in
many laptops might interact badly with any attempts to communicate with the
flash chip and may brick your laptop.
Please make a backup of your flash chip before writing to it.
Please see the flashrom(8) manpage :doc:`classic_cli_manpage`.
Building / installing / packaging
---------------------------------
flashrom is built with **meson**. TLDR:
::
meson setup builddir
meson compile -C builddir
meson test -C builddir
meson install -C builddir
