Sorry to say so, but those recommendations are quite wrong when the goal is to add the support for a new _board_ in the kernel. What you're describing here are roughly the steps to add the support for a new SoC or family of SoC. If what's needed is adding support for a new board that uses an ARM SoC already supported by the kernel, then all what's needed is either writing a Device Tree file (if the ARM SoC in question is supported through the Device Tree) or writing a board file in an existing mach-<foo> folder.
