Add initial support for System Management Agent (SMA) programmer. SMA is a SOC which is working as a side band management on Nvidia server board. One of its functionality is to flash firmware to other components. Test: 1. Build flashrom with this change. 2. Run operation: erase, write, read 3. All operations completed with expected performance. NV_SMA_SPI has been tested with the following SPI flash models: w25r128jw w25r64jv w25q16v Change-Id: I6b2522788db3dcee2b30faff29f605cede8c0eaf Co-Developed-by: Gilbert Chen <gilbertc@nvidia.com> Co-Developed-by: Willie Thai <wthai@nvidia.com> Signed-off-by: Willie Thai <wthai@nvidia.com> Signed-off-by: Gilbert Chen <gilbertc@nvidia.com> Reviewed-on: https://review.coreboot.org/c/flashrom/+/88816 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Peter Marheine <pmarheine@chromium.org> Reviewed-by: Anastasia Klimchuk <aklm@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.
|
|
|
|
Bugs fixed
|
|
==========
|
|
|
|
AMD-based PCs with FCH were unable to read flash contents for internal (BIOS
|
|
flash) chips larger than 16 MB, and attempting to do so could crash the
|
|
system.

Added support
|
|
=============
|
|
|
|
* Intel Wildcat Lake chipset
|
|
* Eon EN25QX128A
|
|
* PUYA P25D80H
|
|
|
|
New features
|
|
============
|
|
|
|
Fail immediately when trying to write/erase wp regions
|
|
------------------------------------------------------
|
|
|
|
This change is done so it's harder for user to brick his own platform.
|
|
Information about read-only regions can easily be missed as flashrom
|
|
can output a lot of information on screen. Even if you notice you might
|
|
not know if one of the regions you requested falls inside read-only
|
|
range, especially if using different names for those regions.
|
|
If you are flashing multiple regions or ones that partially overlap with
|
|
read-only parts then that could result in flashrom failing in the
|
|
middle, leaving you in unknown state.
