This series improves on the configuration options made available to users in the firmware/BIOS setup.
It adds 2 new options, one aimed at limiting the total amount of RAM presented to the OS to 3 GB (currently needed for xHCI on Linux) and the other toggling the provision of the Device Tree, which can be used to force ACPI mode. Combined, these two options remove the need for the ACPI_BASIC_MODE_ENABLE build parameter we were previously using, and allow more fine grained control, including adding the ability for Pi 3 users to enforce ACPI. Finally, some cleanup and harmonization of the user settings menu forms is applied.
