From: Dmitry Eremin-Solenikov Date: Sun, 29 May 2011 13:49:22 +0000 (+0400) Subject: mtd: ATMEL, AVR32: inline nand partition table access X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1754aab9bb869c173aa03b57587256827250e488;p=linux-beck.git mtd: ATMEL, AVR32: inline nand partition table access Currently atmel_nand driver used by AT91 and AVR32 calls a special callback which return nand partition table and number of partitions. However in all boards this callback returns just static data. So drop this callback and make atmel_nand use partition table provided statically via platform_data. Nicolas Ferre: I am in favor for a mainline inclusion through linux-mtd tree. Hans-Christian Egtvedt: I'm fine by sending the changes for AVR32 through linux-mtd Signed-off-by: Dmitry Eremin-Solenikov Acked-by: Hans-Christian Egtvedt Acked-by: Nicolas Ferre Acked-by: Jean-Christophe PLAGNIOL-VILLARD Signed-off-by: Artem Bityutskiy --- diff --git a/arch/arm/mach-at91/board-afeb-9260v1.c b/arch/arm/mach-at91/board-afeb-9260v1.c index b0c796d42e49..a053e915c279 100644 --- a/arch/arm/mach-at91/board-afeb-9260v1.c +++ b/arch/arm/mach-at91/board-afeb-9260v1.c @@ -130,19 +130,14 @@ static struct mtd_partition __initdata afeb9260_nand_partition[] = { }, };
