Daniel Klauer acfda8e923 uboot-sign: Refactor do_deploy prefunc to do_deploy_prepend
When inherited by the u-boot recipe (UBOOT_PN), uboot-sign.bbclass adds
a concat_dtb step, which places additional files into ${DEPLOYDIR}
before do_deploy. By turning this from a prefunc into a part of the normal
do_deploy function, it becomes possible to use
  do_deploy[cleandirs] = "${DEPLOYDIR}"
in the future, without deleting the files produced by concat_dtb.

As before, care is taken to not interfere with the kernel's do_deploy
definition, since concat_dtb was only needed for u-boot.

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.
