ich_spi_send_command() and ich_spi_send_multicommand() will overwrite the "Sector erase" opcode with the opcode for command via reprogram_opcode_on_the_fly(), but not restore it, causing the "Sector erase" opcode may get lost after sending commands, leaving only "Bulk erase" opcode which erase the whole chip available. In the mean time, ich_spi_probe_opcode() used not to report opcodes in POSSIBLE_OPCODES[] but not in curopcodes->opcode[] as supported. Now, if the opcode being probed is not in curopcodes->opcode[] but in POSSIBLE_OPCODES[], it will be reported as supported, and programmed later by ich_spi_send_(multi)command().

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
