A host bridge is allowed to remap BAR addresses using _TRA attribute

When a VGA device is behind such a host bridge and the resource is
translated efifb driver is trying to do ioremap against bus address
rather than the resource address and is failing to probe.
efifb: probing for efifb
efifb: cannot reserve video memory at 0x1e000000
efifb: framebuffer at 0x1e000000, using 1920k, total 1875k
efifb: mode is 800x600x32, linelength=3200, pages=1
efifb: scrolling: redraw
efifb: Truecolor: size=8:8:8:8, shift=24:16:8:0
Use the host bridge offset information to convert bus address to
resource address in the fixup.

I didn't see any messages about these getting picked up for 4.18.
Are they queued on your own branch?
No, you never cc'ed me on them until now.
Ouch, I hoped that you would get it via get_maintainer script. Sorry for
that.
