Based on public Intel 700 Series PCH datasheet, DOC 743835 rev 004. The IDs of IoT chipset SKUs (ending with E) can only be found in "12th Gen Intel® Core™ Processors Family (Formerly Known as Alder Lake -S) for IoT Platforms External Design Specification (EDS) Addendum" DOC 634528 rev 2.7 (NDA). TEST=Probe flash on Z790 chipset. Run the ich_descriptors_tool and check the output is correct as expected.

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.
|
|
|
|
Chipset support
|
|
===============
|
|
Added Raptor Point PCH support.
