[Xen-devel] [PATCH OSSTEST 6/8] ts-kernel-build: Include dtbs in dist file

[Ian Campbell <ian.campbell@xxxxxxxxxx>]

These are installed to $(INSTALL_PATH)/dtbs/$(KERNEL_RELEASE) where
$(INSTALL_PATH) defaults to /boot but we override it to our staging
/boot.

Note that ts-host-install will install the OS dtbs directly into
/boot/dtbs without the subdirectory, so this won't clash and could be
considered a fallback hence I don't propose to move those ones.

The install_dtbs target has been available since v3.14, wherease we
only test v3.16 onwards on ARM, hence no arrangements are needed to
conditionalise this installation over and above the per-arch
arrangements made here.

Having now set $(INSTALL_PATH) I think the "install" target could now
take over the installation of System.map, vmlinux and .config into
/boot but I've not checked this with all historical kernel versions
and don't intend to make this change now.

Remove any previous dist dir on install, otherwise the kernel tends to
create dist/boot/dtbs.old with the previous contents on repeated use.
Seems like good hygiene anyway.
