`.read_resources` and `.set_resources` are the only two device
operations that are considered mandatory. Other function pointers
can be left NULL. Having dedicated no-op implementations for the
two mandatory fields should stop the leaking of no-op pointers to
other fields.

Allow Chrome OS to be enabled for this QEMU target. By default
this does not change anything unless it is selected in the build
configuration, but it makes it possible.
Native VGA init is not forced when Chrome OS is enabled because the
drm-bochs driver does not work with chrome (even the latest upstream
kernel driver with drm atomic support) but it does work with virtio.
The coreboot graphics init needs to match what is selected with qemu
(with -vga std or -vga virtio) which in turn will determine which
kernel driver is used.
A second FMAP is added with both RW-A and RW-B regions which is
required by chromeos.
Recovery mode can be entered by supplying a custom fw_cfg option
when launching qemu: -fw_cfg name=opt/cros/recovery,string=1

- People sometimes have their editor auto-add themselves to files even

- Or they let the editor automatically update the copyright year,

- Who is the copyright holder "The coreboot project Authors"?

Sidestep all these issues by simply not putting these notices in

This CL has changes that allow us to enable a configurable
ramstage, and one change that allows us to minimize PCI
scanning. Minimal scanning is a frequently requested feature.
To enable it, we add two new variables to src/Kconfig
CONFIGURABLE_RAMSTAGE
is the overall variable controlling other options for minimizing the
ramstage.
MINIMAL_PCI_SCANNING is how we indicate we wish to enable minimal
PCI scanning.
Some devices must be scanned in all cases, such as 0:0.0.
To indicate which devices we must scan, we add a new mandatory
keyword to sconfig
It is used in place of on, off, or hidden, and indicates
a device is enabled and mandatory. Mandatory
devices are always scanned. When MINIMAL_PCI_SCANNING is enabled,
ONLY mandatory devices are scanned.
We further add support in src/device/pci_device.c to manage
both MINIMAL_PCI_SCANNING and mandatory devices.
Finally, to show how this works in practice, we add mandatory
keywords to 3 devices on the qemu-q35.
