With a kernel containing both DT and atag support, the diagnostics output when the dtb is missing or corrupt assume that we're trying to boot using atags and the machine ID, and only print the machine ID. This is not useful for diagnosing a missing or corrupt dtb. Move the message into arch/arm/kernel/setup.c, and print the address of the dtb/atag list, and the first 16 bytes of memory of the dtb or atag list. This allows us to see whether the dtb was corrupted in some way, causing the fallback to the machine ID / atag list.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
