Hello,

I took a quick look at the document.  Much of the information still
applies to the latest kernel.  The biggest change that I can see is
that the directories were moved and files renames.  For example

arch/arm/deconfigs/ is now arch/arm/configs
config.in is now Kconfig
include/asm-arm/arch-xxx is moved to arch/arm/mach-xxx/include

By the way, include/asm is a symlink points to
include/asm-arm/arch-xxxx in the older kernels.  The link is created
by the make.  If I were to get Linux to boot on a new board, I would
start by looking at code for a similar target with the same SoC.

I hope that helps.
