2018-08-20common: Add support for Android DT imageSam Protsenko
Android documentation recommends new image format for storing DTB/DTBO files: [1]. To support that format, this patch adds helper functions for Android DTB/DTBO format. In image-android-dt.* files you can find helper functions to work with Android DT image format, such us routines for: - printing the dump of image structure - getting the address and size of desired dtb/dtbo file This patch uses dt_table.h file, that was added in commit 643cefa4d848 ("Import Android's dt_table.h for DT image format") by Alex Deymo.
