The support for PiTFT 28 inch resistive touchscreen is optional
and can be enabled by adding below in local.conf:

MACHINE_FEATURES += "pitft pitft28r”

will this work with all kernel recipes available in layer ?
It works on 3.18+. I just realized that 3.14 support was not removed when we took in 4.4 (so it will not work on that kernel). Since the general policy we have is to support three kernel versions; latest stable (4.4) + two longterm (4.1 and 3.18), I can send up a commit that removes 3.14 support in 'master' within this series.

Thanks for your help to pointing this out!
