Subject: [PATCH 1/3] c6x: add Makefile to invoke syscall table generation script
Date: Mon, 7 Jan 2019 20:22:44 +0530 [thread overview]
Message-ID: <1546872766-3354-2-git-send-email-firoz.khan@linaro.org> (raw)
In-Reply-To: <1546872766-3354-1-git-send-email-firoz.khan@linaro.org>
Add Makefile to invoke the system call table generation script
which is placed in scripts directory as a common location acc-
essible for all the architectures.
scripts/syscallhdr.sh will generate uapi header and scripts-
/syscalltbl.sh will generate kapi header respectively. There
is another scripts scripts/syscallnr.sh can generate total
number of syscall which doesn't invoke from this Makefile.
