From: Hao Zhang <[email protected]> Build recovery kernel image and k2hk-evm dtb image for Keystone II devices.
Normally when kernel is booted by u-boot, u-boot takes care to reserve free memory space in the DTB, which is required for kernel. For recovery image, user has to add the free space manually using dtc compiler.
