From mboxrd@z Thu Jan 1 00:00:00 1970 From: shawn.guo@freescale.com (Shawn Guo) Date: Thu, 9 Dec 2010 23:12:45 +0800 Subject: [PATCH v2 10/15] ARM: mxs: Add static memory mapping In-Reply-To: <1290754154-9428-1-git-send-email-shawn.guo@freescale.com> References: <1290754154-9428-1-git-send-email-shawn.guo@freescale.com> Message-ID: <1291907569-8925-10-git-send-email-shawn.guo@freescale.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Create static memory mapping for MX23 and MX28. Signed-off-by: Shawn Guo --- Changes for v2: - Change the inclusion of hardware.h to mx23.h and mx28.h respectively - Remove the call to mxs_iomux_init() and mxs_arch_reset_init() from map_io callback, and turn them into __initcall, as the call here is a little late. arch/arm/mach-mxs/mm-mx23.c | 45 +++++++++++++++++++++++++++++++++++++++++++ arch/arm/mach-mxs/mm-mx28.c | 45 +++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 90 insertions(+), 0 deletions(-) create mode 100644 arch/arm/mach-mxs/mm-mx23.c create mode 100644 arch/arm/mach-mxs/mm-mx28.c diff --git a/arch/arm/mach-mxs/mm-mx23.c b/arch/arm/mach-mxs/mm-mx23.c new file mode 100644 index 0000000..5148cd6 --- /dev/null +++ b/arch/arm/mach-mxs/mm-mx23.c @@ -0,0 +1,45 @@ +/* + * Copyright 2008-2010 Freescale Semiconductor, Inc.
