Re: [PATCH v8] arm: Add Kconfig entry to select CONFIG_DTB_FILE



Hi Michal,

Currently in order to link existing DTB into Xen image
we need to either specify option CONFIG_DTB_FILE on the
command line or manually add it into .config.
Add Kconfig entry: CONFIG_DTB_FILE
to be able to provide the path to DTB we want to embed
into Xen image. If no path provided - the dtb will not
be embedded.

Remove the line: AFLAGS-y += -DCONFIG_DTB_FILE=\"$(CONFIG_DTB_FILE)\"
as it is not needed since Kconfig will define it in a header
with all the other config options.

Move definition of _sdtb into dtb.S to prevent defining it
if there is no reference to it or if someone protects
_sdtb with #ifdef rather than with .ifnes. If the latter,
we will get a compiler error.

I have committed to my for-next/4.16 branch for now. This will soon reached staging.
