Subject: [U-Boot] [RESEND][PATCH 04/24] sh: cache use jump_to_P2() and back_to_P1() from asm/system.h
Date: Mon, 28 Nov 2016 00:15:16 +0200	[thread overview]
Message-ID: <20161127221536.9577-5-vz@mleia.com> (raw)
In-Reply-To: <20161127221536.9577-1-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.
