puzzled by FILESPATH setting in tipspkernel.inc

puzzled by FILESPATH setting in tipspkernel.inc

[Robert P. J. Day]

  poking around some of the kernel recipes in the meta-ti layer and
i'm a bit baffled by the following in
meta-ti/recipes-kernel/linux/tipspkernel.inc:

# First of all, set own FILESPATH avoiding unnecessary BP and BPN, but adding
# extra level of major version
FILESPATH = "${@base_set_filespath([ "${FILE_DIRNAME}/${PF}", "${FILE_DIRNAME}/${P}", "${FILE_DIRNAME}/${PN}-${PMV}", \
"${FILE_DIRNAME}/${PN}", "${FILE_DIRNAME}/files", "${FILE_DIRNAME}" ], d)}"

  i understand the mechanics of how the above works, but i'm not sure
about that very last element in array: ${FILE_DIRNAME}, all by itself.
is that deliberate? that is, not having any extra level such as ${PF}
or ${P} or "files"? isn't that suggesting that files can be located in
the main directory itself? which doesn't seem to be necessary.

That used to be the case before, but had changed a year ago:
http://cgit.openembedded.org/openembedded-core/commit/?id=3efa13cd76bbd5611805021945fc9def88d9fd93

Anyway, tipspkernel.inc is a deprecated feature and its use is discouraged 
now. It remains present for some old kernel recipes to work.
