v1.4 release already out – Making Pi ServerReady

Pete’s on a roll! Some significant improvements have landed in the latest and greatest release.

https://github.com/pftf/RPi4/releases/tag/v1.4

What’s inside this release?

Add user configurable option to enable/disable 3GiB RAM Limit [tianocore/edk2-platforms@874750a]
Add user configurable option to enable/disable the provision of a Device Tree (to force ACPI) [tianocore/edk2-platforms@da7cb41]
Improve platform configuration layout [tianocore/edk2-platforms@dac18ca]

Assuming you have a 4GiB Pi, you can now boot with with the entire 4GiB available if you run NetBSD-current (generic 64-bit image), which already supports the ACPI interfaces required to make the Pi USB3 controller work with the full 4GiB RAM. Those living on the edge can try this Linux patch.

Note: upstreaming the Linux patch would be a great way to help this project.

Additionally, there’s been some improvements to the setup option layout:

Reorder forms in the order they are most likely to be queried.

Rename Chipset Configuration, making CPU settings more prominent.

New Advanced Configuration. 3GB limit setting is grayed out on 1GB/2GB boards.

As always, read the release notes and usual caveats.
