[Qemu-devel] [PATCH 03/15] sun4u: move ISABus inside of EBusState


From: Mark Cave-Ayland
Subject: [Qemu-devel] [PATCH 03/15] sun4u: move ISABus inside of EBusState
Date: Fri, 17 Nov 2017 13:42:35 +0000

Since the EBus is effectively a PCI-ISA bridge then the underlying ISA bus
should be contained within the PCI bridge itself.
