Hi Eugeniu,

Our platform doesn't store the DTB into the Android image second area, but rather copies the DTB to RAM from a dedicated dtb.img partition [0], prior to booting the Android image by calling bootm.
Similar to [1], we find it useful to just call 'bootm' and have the right DTB being passed to OS (assuming its address has been previously stored in 'fdtaddr' by calling `fdt addr <dtb-addr>`).
Booting Android with DTB from 'fdtaddr' will only occur if:
- No DTB is embedded in the second area of Android image
- 'fdtaddr' points to a valid DTB in RAM

Changes in v2:
- Removed fdt_totalsize() computation, since FDT size verification is only relevant for blobs embedded in U-Boot-supported images
- Link v1: https://patchwork.ozlabs.org/patch/1071591/

We could really use a simple test of Android booting (not the whole process, just the setup and the different cases we support)
