One of many thrilling Coreboot / open-source firmware milestones of 2022 was a Coreboot/Dasharo port to a available Intel Alder Lake motherboard from MSI with the port being carried out by consulting agency 3mdeb. That port began with the MSI PRO Z690-A WiFi DDR4 after which extra just lately centered on the DDR5 variant. That MSI PRO Z690-A WiFi DDR5 help has now been upstreamed into mainline Coreboot.
Again in November 3mdeb launched Dasharo 1.1 as their downstream firmware of Coreboot. That v1.1 launch added help for the DDR5 motherboard whereas on Friday the Coreboot help made it upstream.

It turned out to be a comparatively clean port going from the DDR4 motherboard to the DDR5 model.
The 3mdeb port for this MSI motherboard landed upstream with this commit.
The Dasharo-powered MSI PRO Z690-A WiFi DDR4 continues working properly with Intel Alder Lake processors.
