MX25L12873F datasheet: (no hardware WP)
https://www.mxic.com.tw/Lists/Datasheet/Attachments/8652/MX25L12873F,%203V,%20128Mb,%20v1.2.pdf
Status register: page 31(BP0~BP3, SRWD)
Configuration register: page 32 table 7 (TB)
Security register: page 60 table 9 (WPSEL)

Splits the MX25L12833F/MX25L12835F/MX25L12845E/MX25L12865E/MX25L12873F
group into three subgroups:
* MX25L12833F: This chip have the configuration register and WP tested
* MX25L12835F/MX25L12873F: These chips have the configuration register.
* MX25L12845E/MX25L12865E: These chips don't have the configuration
  register.

Tests the write protect functionality on the MX25L12833F chip only.

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`.
