I boot tested this on JunoR2 with a recent build of Tianocore EDK2.
It works enough to boot the machine with PCIe attached sata, and
ethernet, but is throwing messages like:
[ 1.094643] pci 0000:00:00.0: BAR 13: no space for [io size 0x2000]
[ 1.101022] pci 0000:00:00.0: BAR 13: failed to assign [io size 0x2000]
Its also throwing:
[ 1.029958] pci 0000:00:00.0: of_irq_parse_pci() failed with rc=-22
[ 1.052784] pci 0000:00:00.0: of_irq_parse_pci() failed with rc=-22
(see other response for the DwordIo resource i'm using).
