[OE-core] [PATCH 0/4] add wic based image installer

[Lee, Chee Yang]

I couldn’t figure out how to make it with sdimage-bootpart.wks, can you tell me what did you set for IMAGE_BOOT_FILES ?

To further explain the idea,  I'm trying to use the new source plugin and .wks.in to build a wic image that "mimic" a hddimg, where I can dd the wic image to an USB drive and use that usb drive to install image to my target machine (like hddimg did ). 
first partition allow to boot into initramfs and it will execute the install script. The script will then install system-boot configuration, efi, kernel, rootfs.img and initrd from second partition to target machine. 

My sample image here:

    I ended up using sdimage-bootpart.wks and IMAGE_BOOT_FILES to populate
    the partition as needed.  I can't paste the exact image as it was done
    for a customer.
