From: Pierre Gondois <pierre.gond...@arm.com>
Booting a Juno-r0 with a DEBUG build triggers an ASSERT when
processing the library constructors of:
MdeModulePkg/Bus/Pci/PciHostBridgeDxe/PciHostBridgeDxe.inf
JunoPciHostBridgeLib.inf::HWPciRbInit() returns an error code
as Juno-r0 doesn't support PCIe.
Check Juno's revision in HWPciRbInit() before setting up the
PCIe root complex.
