From 8cdae51aa951e22bc9134cc94c30d1206c84ea8e Mon Sep 17 00:00:00 2001 From: Andrew Victor Date: Mon, 6 Oct 2008 20:05:35 +0100 Subject: [ARM] 5289/1: [AT91] Convert boards to use sam9_smc_configure() Convert the SAM9 and CAP9 board-specific files to make use of the sam9_smc_configure() method to configure the memory-controller for external peripherals. The following boards have been modified: cam60 : NAND cap9adk : NAND, NOR qil-a9260 : NAND sam9-l9260 : NAND sam9260ek : NAND sam9261ek : DM9000 Ethernet, NAND sam9263 : NAND sam9g20ek : NAND sam9rlek : NAND usb-a9260 : NAND usb-a9263 .: NAND Signed-off-by: Andrew Victor Signed-off-by: Russell King --- arch/arm/mach-at91/board-cam60.c | 30 ++++++++++++- arch/arm/mach-at91/board-cap9adk.c | 72 +++++++++++++++++++++++++------ arch/arm/mach-at91/board-qil-a9260.c | 35 ++++++++++++--- arch/arm/mach-at91/board-sam9-l9260.c | 35 ++++++++++++--- arch/arm/mach-at91/board-sam9260ek.c | 37 +++++++++++++++- arch/arm/mach-at91/board-sam9261ek.c | 80 ++++++++++++++++++++++++++++------- arch/arm/mach-at91/board-sam9263ek.c | 36 +++++++++++++++- arch/arm/mach-at91/board-sam9g20ek.c | 36 +++++++++++++++- arch/arm/mach-at91/board-sam9rlek.c | 32 ++++++++++++-- arch/arm/mach-at91/board-usb-a9260.c | 35 ++++++++++++--- arch/arm/mach-at91/board-usb-a9263.c | 36 +++++++++++++--- 11 files changed, 405 insertions(+), 59 deletions(-) (limited to 'arch/arm/mach-at91') diff --git a/arch/arm/mach-at91/board-cam60.c b/arch/arm/mach-at91/board-cam60.c index cdddca54b93..d3ba29c5d8c 100644 --- a/arch/arm/mach-at91/board-cam60.c +++ b/arch/arm/mach-at91/board-cam60.c @@ -39,7 +39,9 @@ #include #include +#include +#include "sam9_smc.h" #include "generic.h" @@ -151,6 +153,32 @@ static struct atmel_nand_data __initdata cam60_nand_data = { .partition_info = nand_partitions, };
