Darren Hart 67cfa74744 bootimg: Use the same OS files for each boot method 
Fixes [YOCTO #1951]

The do_bootimg code can generate hybrid efi+pcbios images (syslinux and
grub-efi) to boot on platforms with both EFI and legacy BIOS options. The
current implementation copies the kernel, initrd, and rootfs twice,
unnecessarily bloating the image size. This is an especially egregious bug
on -sato images.

Update the classes to use a common install of the kernel, initrd, and rootfs to
the root of the boot media. Grub-efi, syslinux, and isolinux can all reference
this location explicitly with a leading slash.

Tested with an EFI+PCBIOS image in both EFI and PCBIOS boot modes on two
platforms. No ISO image testing was performed.

Poky
====

Poky is an integration of various components to form a complete prepackaged
build system and development environment. It features support for building
customised embedded device style images. There are reference demo images
featuring a X11/Matchbox/GTK themed UI called Sato. The system supports
cross-architecture application development using QEMU emulation and a
standalone toolchain and SDK with IDE integration.

Additional information on the specifics of hardware that Poky supports
is available in README.hardware. Further hardware support can easily be added
in the form of layers which extend the systems capabilities in a modular way.

As an integration layer Poky consists of several upstream projects such as 
BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information 
e.g. for the hardware support. Poky is in turn a component of the Yocto Project.

The Yocto Project has extensive documentation about the system including a 
reference manual which can be found at:
    http://yoctoproject.org/community/documentation

OpenEmbedded-Core is a layer containing the core metadata for current versions
of OpenEmbedded. It is distro-less (can build a functional image with
DISTRO = "") and contains only emulated machine support.

For information about OpenEmbedded, see the OpenEmbedded website:
