Rob Herring d5615e472d builddeb: Fix inclusion of dtbs in debian package
Commit 37c8a5fafa ("kbuild: consolidate Devicetree dtb build rules")
moved the location of 'dtbs_install' target which caused dtbs to not be
installed when building debian package with 'bindeb-pkg' target. Update
the builddeb script to use the same logic that determines if there's a
'dtbs_install' target which is presence of the arch dts directory. Also,
use CONFIG_OF_EARLY_FLATTREE instead of CONFIG_OF as that's a better
indication of whether we are building dtbs.

This commit will also have the side effect of installing dtbs on any
arch that has dts files. Previously, it was dependent on whether the
arch defined 'dtbs_install'.

Copyright 2003 Wichert Akkerman wichert@wiggy.net

Simple script to generate a deb package for a Linux kernel. All the

complexity of what to do with a kernel after it is installed or removed

is left to other scripts and packages: they can install scripts in the

/etc/kernel/{pre,post}{inst,rm}.d/ directories (or an alternative location

specified in KDEB_HOOKDIR) that will be called on package install and

removal.

Install the maintainer scripts

Note: hook scripts under /etc/kernel are also executed by official Debian

kernel packages, as well as kernel packages built using make-kpkg.

make-kpkg sets $INITRD to indicate whether an initramfs is wanted, and

so do we; recent versions of dracut and initramfs-tools will obey this.
