Add Device: W541

[Thrilleratplay]

I have a W541 currently running coreboot 4.15 and Tianocore. I need to stream line the process for mrc.bin

• Create SeaBIOS build
• Add unit tests

@gellatofresh I need to make a few updates but I am using Tianocore on my W541. I have not tested SeaBIOS

That is great. I'm curious what the notable issues are currently. Have you users it with the 1620p display?

I have a 3K IPS (2880 x 1620) screen and it works at the full resolution without any issues.

Generally, I have had stability issues with this machine for the past few months. Most have been isolated to Linux bugs with ZFS, the enabling a feature on a specific model of SSD and bad memory (likely caused by the constant deadlocking by ZFS). The last ones are related to hardware rendering using the Intel GPU on Xorg without the VGA blob. This was not an issue on my X230 but the higher resolution or newer generation of GPU may have caused this on the W541. I am trying different Xorg config settings to see if this can mitigated without looking sluggish.

With the exception of the Intel GPU, these are problems outside of coreboot and I am less worried about creating stability issues for others.

@gellatofresh I pushed the latest rendition of the W541 Tianocore build into the W541_tianocore branch. The custom boot image does not work but everything else should be fine.

Thanks much man. Let me see what I can do to contribute. Should have some time soon.

Currently am waiting for the next coreboot-sdk release, which should include the needed programs to extract the mrc.bin automatically.
