Peter Maydell 2070ef1c37 boards.h: Define new flag ignore_memory_transaction_failures ... Define a new MachineClass field ignore_memory_transaction_failures. If this is flag is true then the CPU will ignore memory transaction failures which should cause the CPU to take an exception due to an access to an unassigned physical address; the transaction will instead return zero (for a read) or be ignored (for a write). This should be set only by legacy board models which rely on the old RAZ/WI behaviour for handling devices that QEMU does not yet model. New board models should instead use "unimplemented-device" for all memory ranges where the guest will attempt to probe for a device that QEMU doesn't implement and a stub device is required. We need this for ARM boards, where we're about to implement support for generating external aborts on memory transaction failures. Too many of our legacy board models rely on the RAZ/WI behaviour and we would break currently working guests when their "probe for device" code provoked an external abort rather than a RAZ.
