Impliment the vhost-crypto's funtions, such as startup, stop and notification etc. Introduce an enum QCryptoCryptoDevBackendOptionsType in order to identify the cryptodev vhost backend is vhost-user or vhost-kernel-module (If exist).

2018-03-01vhost: avoid to start/stop virtqueue which is not readyJia He
In our Armv8a server, we try to configure the vhost scsi but fail to boot up the guest (-machine virt-2.10). The guest's boot failure is very early, even earlier than grub. There are 3 virtqueues (ctrl, event and cmd) for virtio scsi device, but ovmf and seabios will only set the physical address for the 3rd one (cmd). Then in vhost_virtqueue_start(), virtio_queue_get_desc_addr will be 0 for ctrl and event vq when qemu negotiates with ovmf. So vhost_memory_map fails with ENOMEM. This patch just fixs it by early quitting the virtqueue start/stop when virtio_queue_get_desc_addr is 0. Btw, after guest kernel starts, all the 3 queues will be initialized and set address correctly. Already tested on Arm64 and X86_64 qemu.

2018-02-27loader: don't perform overlapping address check for memory region ROM imagesMark Cave-Ayland
All memory region ROM images have a base address of 0 which causes the overlapping address check to fail if more than one memory region ROM image is present, or an existing ROM image is loaded at address 0. Make sure that we ignore the overlapping address check in rom_check_and_register_reset() if this is a memory region ROM image. In particular this fixes the "rom: requested regions overlap" error on startup when trying to run qemu-system-sparc with a -kernel image since commit 7497638642: "tcx: switch to load_image_mr() and remove prom_addr hack".

2018-02-22Fix ast2500 protection register emulationHugo Landau
Some register blocks of the ast2500 are protected by protection key registers which require the right magic value to be written to those registers to allow those registers to be mutated. Register manuals indicate that writing the correct magic value to these registers should cause subsequent reads from those values to return 1, and writing any other value should cause subsequent reads to return 0. Previously, qemu implemented these registers incorrectly: the registers were handled as simple memory, meaning that writing some value x to a protection key register would result in subsequent reads from that register returning the same value x. The protection was implemented by ensuring that the current value of that register equaled the magic value. This modifies qemu to have the correct behaviour: attempts to write to a ast2500 protection register results in a transition to 1 or 0 depending on whether the written value is the correct magic. The protection logic is updated to ensure that the value of the register is nonzero. This bug caused deadlocks with u-boot HEAD: when u-boot is done with a protectable register block, it attempts to lock it by writing the bitwise inverse of the correct magic value, and then spinning forever until the register reads as zero. Since qemu implemented writes to these registers as ordinary memory writes, writing the inverse of the magic value resulted in subsequent reads returning that value, leading to u-boot spinning forever.
