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