Hi Mark,

`hope we talk about the same context:
The 1GB DMA range fix from Rob in https://reviews.freebsd.org/D26344 <https://reviews.freebsd.org/D26344>
has NOTHING to do with UEFI/ACPI.
It addresses  the pcie-driver for fdt(u-boot).
While there is probably some inheritances in the USB/pcie-chain:
pcie is NOT exposed to the OS by rpi4Uefi-dev.


Regards

Klaus
