This is needed for Linux/arm64, which can only reliably deal with devices that are unable to perform DMA to the entire 32-bit address range if it can discover their existence early during boot, and this is before the ACPI interpreter is up and running (which rules out calling the _DMA method of the XHC0 object) End Quote https://github.com/pftf/RPi4/releases/tag/v1.21 includes this change. (It also updates the RPI4B firmware to quit using the broken start4.elf that corrupted Device Tree information.) =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
