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>

Recent development (unreleased)
|
|
===============================
|
|
|
|
This document describes the major changes that are expected to be included in
|
|
the next release of flashrom and which are currently only available by source
|
|
code checkout (see :doc:`../dev_guide/building_from_source`). These changes
|
|
may be further revised before the next release.
|
|
|
|
Known issues
|
|
============
|
|
|
|
AMD-based PCs with FCH are unable to read flash contents for internal (BIOS
|
|
flash) chips larger than 16 MB, and attempting to do so may crash the system.
|
|
Systems with AMD "Promontory" IO extenders (mostly "Zen" desktop platforms) are
|
|
not currently supported.

|
Build only supported with Meson
|
|
===============================
|
|
|
|
As documented in the :doc:`v1.4 release notes <v_1_4>`, support for building
|
|
flashrom with make has been removed; all Makefiles have been deleted. Meson is
|
|
now the only supported tool for building flashrom from source.
|
|
|
|
New Feature
|
|
===========
|
|
Libpci 3.13.0 and onwards support ECAM to access pci registers. Flashrom will
|
|
be moved to ECAM from IO port 0xcf8/0xcfc if the libpci version is >= 3.13.0.
|
|
The ECAM has been supported for a very long time, most platforms should support
|
|
it. For those platforms don't support ECAM, libpci will terminate the process by
|
|
exit.
