Make the filename parameter directly following -r/-w/-v optional, since the -i parameter allows the image to be written to be sourced from multiple files, regions to be read from flash and written to separate image files, and regions to be verified using an image file only containing that region. Since the filename parameter following -w/-v was ignored when a filename was specified following `-i <region>:<filename>`, this patch essentially removes the requirement to provide an unused parameter. Based on https://review.coreboot.org/c/flashrom/+/52362. TEST=run the following commands on a supported board: flashrom -p internal -r /tmp/coreboot.rom flashrom -p internal -r --ifd -i bios:/tmp/coreboot.rom flashrom -p internal -r /tmp/coreboot.rom --ifd -i bios:/tmp/bios.bin flashrom -p internal -w /tmp/coreboot.rom flashrom -p internal -w --ifd -i bios:/tmp/coreboot.rom flashrom -p internal -w /tmp/coreboot.rom --ifd -i bios:/tmp/bios.bin flashrom -p internal -v /tmp/coreboot.rom flashrom -p internal -v --ifd -i bios:/tmp/coreboot.rom flashrom -p internal -v /tmp/coreboot.rom --ifd -i bios:/tmp/bios.bin Change-Id: I6eba095d478f1a7bdbc3854627a656f93dd9e452 Signed-off-by: Matt DeVillier <matt.devillier@gmail.com> Reviewed-on: https://review.coreboot.org/c/flashrom/+/85159 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Anastasia Klimchuk <aklm@chromium.org>
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
