Subject: [U-Boot] [PATCH 4/6] sh: cache use jump_to_P2() and back_to_P1() from asm/system.h
Date: Mon, 8 Aug 2016 21:13:20 +0300 [thread overview]
Message-ID: <1470680002-16354-5-git-send-email-vz@mleia.com> (raw)
In-Reply-To: <1470680002-16354-1-git-send-email-vz@mleia.com>
Both jump_to_P2() and back_to_P1() functions are found in asm/system.h
header file and functionally they are the same, don't redefine them.
