Dmitry Baryshkov b9bffd7650 linux-firmware: add support for building snapshots
In some cases it is useful to be able to test the snapshot of
linux-firmware (e.g. to test if the updated firmware works on the
particular hardware). Allow building the linux-firmware snapshots.

To switch to the most recent branch, add the following lines to the
local.conf file:

PREFERRED_VERSION_linux-firmware = "1:20220509+git%"
SRCREV:class-devupstream = "${AUTOREV}"
WHENCE_CHKSUM:class-devupstream:pn-linux-firmware = "4288aad55d189fa225d492526b8406d5"

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
