In the latest pciutils(v3.13.0), it supports accessing pci registers by ecam. This patch uses libpci version check to decide whether flashrom calls libpci and use 0xcf8/0xcfc or ecam to access pci registers. BUG=b:359813524 TEST=with libpci >= 3.13.0, flashrom is working with ECAM access Change-Id: I4549f87c8b01da0a1d3d8ce0b3b75c1f5fa2cbab Signed-off-by: Kane Chen <kane.chen@intel.com> Reviewed-on: https://review.coreboot.org/c/flashrom/+/83896 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Hsuan-ting Chen <roccochen@google.com> Reviewed-by: Peter Marheine <pmarheine@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
