Guillaume Champagne b9e8b3cc49 image-live.bbclass: order do_bootimg after do_rootfs
do_bootimg expects IMGDEPLOYDIR to exist, since it stores its artifacts
there. Therefore, do_bootimg should run after do_rootfs because
IMGDEPLOYDIR is created before do_rootfs runs since IMGDEPLOYDIR is
contained in do_rootfs' [cleandirs] varflag.

When do_bootimg depends on ${PN}:do_image_${LIVE_ROOTFS_TYPE},
do_bootimg is correctly ordered after do_rootfs because
do_image_${FSTYPE} tasks are added after do_image and do_image itself is
added after do_rootfs.

However, when do_bootimg doesn't depend on
${PN}:do_image_${LIVE_ROOTFS_TYPE}
(introduced by: 96f47c39f1d17f073243913d524bde84add41d8f), do_bootimg
can run before do_rootfs, thus before IMGDEPLOYDIR is created. To
avoid this situation, do_bootimg is now explicitly ordered after
do_rootfs.

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.
