Add virtual provider for dtb. This class can be used to generate dtb from static devicetree, for reference see meta-xilinx layer meta-xilinx/meta-xilinx-bsp/recipes-bsp/device-tree/device-tree.bb By providing a virtual provider we can use it to differentiate between in-kernel dtb or an external one. This can be set in local.conf as PREFERRED_PROVIDER_virtual/dtb = "devicetree" (From OE-Core rev: a7d52dbffd0da95de82d910c595a6c27d9b2ad0d) Signed-off-by: Manjukumar Matha <manjukumar.harthikote-matha@xilinx.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
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.
