devicetree: document the qemu and virtio vendor prefixes
devicetree: document ARM bindings for QEMU's Firmware Config interface
The QEMU open source machine emulator and virtualizer presents firmware
and operating systems running in virtual machines (guests) with purely
virtual hardware (ie. hardware that has never existed in physical form).
Since QEMU exposes some of these devices in a DTB, it makes sense to
define qemu
Peter Maydell suggested that we describe new devices / DTB nodes in the
kernel Documentation tree that we expose to arm virt guests in QEMU.
Although the kernel is not required to access the fw_cfg interface,
Documentation/devicetree/bindings/arm is probably the best central spot
to keep the
fw_cfg already supports exposure over MMIO (used in ppc/mac_newworld.c,
ppc/mac_oldworld.c, sparc/sun4m.c); we can easily add it to the virt
board.
The mmio register block of fw_cfg is advertized in the device tree. As
base address we pick 0x0902, which conforms to the comment preceding

Two fields are added in arm_boot_info (dtb_start and dtb_limit). The
