[U-Boot] [PATCH 0/5] Use Android DT image format for TI boards

[Sam Protsenko]

Android documentation recommends using new image format for storing dtb
and dtbo files: [1]. Using that format, we can pack several dtb files to
dtb.img, and also pack several dtbo files to dtbo.img. Then those images
should be flashed to eMMC partitions, called "dtb" and "dtbo"
respectively.

This patch series introduces support for mentioned Android DT image
format, adds "dtimg" command to deal with that image format from U-Boot
shell, and provides new Android boot scheme to TI boards (AM57x and DRA7
boards). So with this patch series we will have next procedure for
Android boot:
 1. Read next images from eMMC partitions to RAM:
    - boot.img
    - dtb.img
    - dtbo.img
 2. Take addresses of desired dtb/dtbo files from that images (for
    current board)
 3. Apply dtbo overlays to main dtb, if needed
 4. Boot the kernel from Android boot image, using resulting dtb

It was tested on X15 and AM57x EVM boards.
