There is nothing arch specific about building dtb files other than their
location under /arch/*/boot/dts/. Keeping each arch aligned is a pain.
The dependencies and supported targets are all slightly different.
Also, a cross-compiler for each arch is needed, but really the host
compiler
This series addresses a couple of issues I have with building dts files.
First, the ability to build all the dts files in the tree. This has been
supported on most arches for some time with powerpc being the main
exception. The reason powerpc wasn't supported was it needed a change
in the
Prefer _THIS_IP_ defined in linux/kernel.h.
Most definitions of current_text_addr were the same as _THIS_IP_, but
a few archs had inline assembly instead.
This patch removes the final call site of current_text_addr, making all
of the definitions dead code.
