The rcw source code had been migrated to codeaurora for LSDK-18.06 release and the future release. The source code had also involved ls1012ardb/ls1012afrdm/ ls1088ardb/ls2088ardb rcw, so we updated ls-rcw to LSDK-18.06, reworked the makefile and dropped ls-rcw-bin package in this patch. Also reworked ls-rcw patch to adapt to the latest source code. Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com>
