Marc-André Lureau	8741781157	hw/vfio: add ramfb migration support ... Add a "VFIODisplay" subsection whenever "x-ramfb-migrate" is turned on. Turn it off by default on machines <= 8.1 for compatibility reasons.

Gerd Hoffmann	2fc979cb9d	Revert "hw/display/ramfb: initialize fw-config space with xres/ yres" ... This reverts commit f79081b4b7. Patch has broken byteorder handling: RAMFBCfg fields are in bigendian byteorder, the reset function doesn't care so native byteorder is used instead. Given this went unnoticed so far the feature is obviously unused, so just revert the patch.

Hou Qiming	f79081b4b7	hw/display/ramfb: initialize fw-config space with xres/ yres ... If xres / yres were specified in QEMU command line, write them as an initial resolution to the fw-config space on guest reset, which a later BIOS / OVMF patch can take advantage of.

Gerd Hoffmann	7f623d0834	stubs: add ramfb ... Needed to make sure code using ramfb (vfio) compiles properly even on platforms without fw_cfg (and therefore no ramfb) support.
