Patrick Ohly aab33ec877 rootfs-postcommands.bbclass: ensure that rootfs gets mounted ro
When read-only-rootfs is active, we need to ensure that the rootfs
does not get mounted read/write by the kernel or initramfs. Adding
"ro" to the boot parameters achieves that.

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.
