duplicate dtbs in deploydir

[Jonathan Richardson]

Hi,

Just wondering why there are 2 symlinks to a dtb in the deploy dir. It has
been like this for a while but creates a lot of clutter. It's from the
last 2 lines in kernel-devicetree.bbclass. I was going to clean it up but
wondered if it's there for a reason.. Thanks.

do_deploy_append() {
	for dtbf in ${KERNEL_DEVICETREE}; do
		dtb=`normalize_dtb "$dtbf"`
		dtb_ext=${dtb##*.}
		dtb_base_name=`basename $dtb .$dtb_ext`
		install -d $deployDir
		install -m 0644
${D}/${KERNEL_IMAGEDEST}/$dtb_base_name.$dtb_ext
$deployDir/$dtb_base_name-${KERNEL_DTB_NAME}.$dtb_ext
		ln -sf $dtb_base_name-${KERNEL_DTB_NAME}.$dtb_ext
$deployDir/$dtb_base_name.$dtb_ext
		ln -sf $dtb_base_name-${KERNEL_DTB_NAME}.$dtb_ext
$deployDir/$dtb_base_name-${KERNEL_DTB_LINK_NAME}.$dtb_ext

Some automated testing code relies upon symlinks in the deploy
directory to find the latest dtb/image/whatever. The symlink names
usually remove elements like date/timestamps.

Whether that is the case here and whether its used or not I'm not sure
but that is why you see these as it saves pattern matching which may
change over time.

Cheers,

Richard
