Write a recipe <oem>-image-tools-native.bb under recipes-tools to copy all the tools, binaries and scripts needed to create custom oem image to the staging binary directory

• This recipe should fetch all the sources from the GIT repo
• Example name space for the GIT repo where you should place all the tools like permission files, authentication keys etc - “rdk/devices/<OEM>/<OEM_device>/tools”
• Example namespace for the GIT repo to keep all the binaries (crcsum etc) - “rdk/devices/<OEM>/<OEM_device>/bin”
• This recipe will have only one task – do_install, which copies all the necessary files to create oem images to staging binary directory
• "inherit native" this class would short-circuit all the target build and strip tasks.

Write a bbclass - oem-image.bbclass 

• Add oem-image-tools as DEPENDS
• In this class add a task "create_oem_image" to create the oem specific images - "addtask create_oem_image after do_rootfs before do_build"
• Copy all the tools and files needed from STAGING_BINDIR_NATIVE to working directory, which were copied by <oem>-image-tools-native.bb
• Once copied this task will have the logic to create the custom oem images
• After creating the custom oem images, copy them to DEPLOY_DIR_IMAGE
• In recipe add "create_oem_image[nostamp] = "1"", this allows task to run every-time on every run of bitbake.
• Add create_oem_image[depends] += "${PN}:do_rootfs" to make sure the do_rootfs task is re-run every time before executing the task - create_oem_image.
• Make this class inherit by all the rdk image recipes,
   rdk-generic-mediaserver-image.bbappend: inherit oem-image,comcast-mediaclient-image.bbappend:inherit oem-image,comcast-hybrid-image.bbappend:inherit oem-image,rdk-generic-hybrid-image.bbappend:inherit oem-image, core-image-minimal.bbappend:inherit oem-image,rdk-generic-image.bbappend:inherit oem-image,rdk-generic-mediaclient-image.bbappend:inherit oem-image.
