From be64d7776bcc48a542acf1f74765a3930692cef4 Mon Sep 17 00:00:00 2001 From: Mark Cave-Ayland Date: Sun, 5 Aug 2018 12:28:49 +0100 Subject: [PATCH 2/3] sysbus: always allow explicit_ofw_unit_address() to override address generation Some SysBusDevices either use sysbus_init_mmio() without sysbus_mmio_map() or the first MMIO memory region doesn't represent the bus address, causing a firmware device path with an invalid address to be generated. SysBusDeviceClass does provide a virtual explicit_ofw_unit_address() method that can be used to override this process, but it was originally intended only as as a fallback option meaning that any existing MMIO memory regions still take priority whilst determining the firmware device address. There is currently only one user of explicit_ofw_unit_address() and that is the PCI expander bridge (PXB) device which has no MMIO/PIO resources defined. This enables us to allow explicit_ofw_unit_address() to take priority without affecting backwards compatibility, allowing the address to be customised as required.

Since the majority of bootdevice nodes for these machines either do not have a separate disk node or require different (custom) names then it is much easier for processing to just disable all suffixes for a particular machine. Introduce a new ignore_boot_device_suffixes MachineClass property to control bootdevice suffix generation, defaulting to false in order to preserve compatibility.
