86 * Prepares complete device tree blob for current board (for Android boot).
88 * Boot image or recovery image should be loaded into $loadaddr prior to running
89 * these commands. The logic of these commnads is next:
91 * 1. Read correct DTB for current SoC/board from boot image in $loadaddr
93 * 2. Merge all needed DTBO for current board from 'dtbo' partition into read
95 * 3. User should provide $fdtaddr as 3rd argument to 'bootm'
