Subject: [U-Boot] [PATCH 03/10] ARM: PSCI: export common PSCI function declarations for C code
Date: Mon, 23 May 2016 20:41:39 +0800 [thread overview]
Message-ID: <1464007306-30269-4-git-send-email-wens@csie.org> (raw)
In-Reply-To: <1464007306-30269-1-git-send-email-wens@csie.org>
Some common PSCI functions are written in assembly, but it should be
possible to use them from C code.
Add function declarations for C code to consume.
