-Subject: [PATCH] PCI: brcmstb: Wait for Raspberry Pi's firmware when present
-
-xHCI's PCI fixup, run at the end of pcie-brcmstb's probe, depends on
-RPi4's VideoCore firmware interface to be up and running. It's possible
-for both initializations to race, so make sure it's available prior to
-starting.
