From 50899183c933e31b1a43de1c4cc7a9085a417d96 Mon Sep 17 00:00:00 2001 From: pekon gupta Date: Fri, 22 Nov 2013 16:53:26 +0530 Subject: [PATCH] mtd: nand: omap: remove redundant platform specific header: arch-xx/omap_gpmc.h Currently there are two sets of omap_gpmc.h header files (a) arch/arm/include/asm/omap_gpmc.h common header file for all platforms, containing defines and declarations used by GPMC NAND driver. (b) arch/arm/include/asm/arch-xx/omap_gpmc.h SoC platform specific header file containing defines like ECC layout. This patch removes platform specific arch-xx/omap_gpmc.c because: - GPMC hardware engine is common for all SoC platforms hence only (a) is enough - ECC layout is now defined in omap_nand.c driver itself based on ecc-scheme selected. Hence all ECC layout declarations in (b) are redundant. Build tested using: ./MAKEALL -s am33xx -s omap3 -s omap4 -s omap5 Signed-off-by: Pekon Gupta --- arch/arm/include/asm/arch-am33xx/omap_gpmc.h | 48 -------------------- arch/arm/include/asm/arch-omap3/mem.h | 10 ++++ arch/arm/include/asm/arch-omap3/omap_gpmc.h | 36 --------------- arch/arm/include/asm/omap_gpmc.h | 2 - 4 files changed, 10 insertions(+), 86 deletions(-) delete mode 100644 arch/arm/include/asm/arch-am33xx/omap_gpmc.h delete mode 100644 arch/arm/include/asm/arch-omap3/omap_gpmc.h diff --git a/arch/arm/include/asm/arch-am33xx/omap_gpmc.h b/arch/arm/include/asm/arch-am33xx/omap_gpmc.h deleted file mode 100644 index 00ad1d0672..0000000000 --- a/arch/arm/include/asm/arch-am33xx/omap_gpmc.h +++ /dev/null @@ -1,48 +0,0 @@ -/* - * (C) Copyright 2004-2008 Texas Instruments, - * Rohit Choraria - * - * SPDX-License-Identifier: GPL-2.0+ - */ -#ifndef __ASM_ARCH_OMAP_GPMC_H -#define __ASM_ARCH_OMAP_GPMC_H - -/* These GPMC_NAND_HW_BCHx_ECC_LAYOUT defines are based on AM33xx ELM */ -#define GPMC_NAND_HW_BCH4_ECC_LAYOUT {\ - .eccbytes = 32,\ - .eccpos = {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15,\ - 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27,\ - 28, 29, 30, 31, 32, 33},\ - .oobfree = {\ - {.offset = 34,\ - .length = 30 } } \ -} - -#define GPMC_NAND_HW_BCH8_ECC_LAYOUT {\ - .eccbytes = 56,\ - .eccpos = {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15,\ - 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27,\ - 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39,\ - 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51,\ - 52, 53, 54, 55, 56, 57},\ - .oobfree = {\ - {.offset = 58,\ - .length = 6 } } \ -} - -#define GPMC_NAND_HW_BCH16_ECC_LAYOUT {\ - .eccbytes = 104,\ - .eccpos = {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15,\ - 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27,\ - 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39,\ - 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51,\ - 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63,\ - 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75,\ - 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87,\ - 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99,\ - 100, 101, 102, 103, 104, 105},\ - .oobfree = {\ - {.offset = 106,\ - .length = 8 } } \ -} -#endif /* __ASM_ARCH_OMAP_GPMC_H */ diff --git a/arch/arm/include/asm/arch-omap3/mem.h b/arch/arm/include/asm/arch-omap3/mem.h index bcc22c43e1..18041913c4 100644 --- a/arch/arm/include/asm/arch-omap3/mem.h +++ b/arch/arm/include/asm/arch-omap3/mem.h @@ -419,6 +419,16 @@ enum { #define NET_GPMC_CONFIG6 0x00000FCF #define NET_GPMC_CONFIG7 0x00000f6c +/* GPMC CS configuration for an SMSC LAN9221 ethernet controller */ +#define NET_LAN9221_GPMC_CONFIG1 0x00001000 +#define NET_LAN9221_GPMC_CONFIG2 0x00060700 +#define NET_LAN9221_GPMC_CONFIG3 0x00020201 +#define NET_LAN9221_GPMC_CONFIG4 0x06000700 +#define NET_LAN9221_GPMC_CONFIG5 0x0006090A +#define NET_LAN9221_GPMC_CONFIG6 0x87030000 +#define NET_LAN9221_GPMC_CONFIG7 0x00000f6c + + /* max number of GPMC Chip Selects */ #define GPMC_MAX_CS 8 /* max number of GPMC regs */ diff --git a/arch/arm/include/asm/arch-omap3/omap_gpmc.h b/arch/arm/include/asm/arch-omap3/omap_gpmc.h deleted file mode 100644 index bf2321932a..0000000000 --- a/arch/arm/include/asm/arch-omap3/omap_gpmc.h +++ /dev/null @@ -1,36 +0,0 @@ -/* - * (C) Copyright 2004-2008 Texas Instruments, - * Rohit Choraria - * - * SPDX-License-Identifier: GPL-2.0+ - */ -#ifndef __ASM_ARCH_OMAP_GPMC_H -#define __ASM_ARCH_OMAP_GPMC_H - -/* - * These GPMC_NAND_HW_BCHx_ECC_LAYOUT defines using the BCH library. - * The OOB layout was first defined by linx kernel in commit - * 0e618ef0a6a33cf7ef96c2c824402088dd8ef48c, we have to reuse it here cause - * we want to be compatible. - */ -#define GPMC_NAND_HW_BCH8_ECC_LAYOUT {\ - .eccbytes = 56,\ - .eccpos = {12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22,\ - 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36,\ - 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50,\ - 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63},\ - .oobfree = {\ - {.offset = 2,\ - .length = 10 } } \ -} - -/* GPMC CS configuration for an SMSC LAN9221 ethernet controller */ -#define NET_LAN9221_GPMC_CONFIG1 0x00001000 -#define NET_LAN9221_GPMC_CONFIG2 0x00060700 -#define NET_LAN9221_GPMC_CONFIG3 0x00020201 -#define NET_LAN9221_GPMC_CONFIG4 0x06000700 -#define NET_LAN9221_GPMC_CONFIG5 0x0006090A -#define NET_LAN9221_GPMC_CONFIG6 0x87030000 -#define NET_LAN9221_GPMC_CONFIG7 0x00000f6c - -#endif /* __ASM_ARCH_OMAP_GPMC_H */ diff --git a/arch/arm/include/asm/omap_gpmc.h b/arch/arm/include/asm/omap_gpmc.h index 6ce5e65a8a..5250109a5b 100644 --- a/arch/arm/include/asm/omap_gpmc.h +++ b/arch/arm/include/asm/omap_gpmc.h @@ -9,8 +9,6 @@ #ifndef __ASM_OMAP_GPMC_H #define __ASM_OMAP_GPMC_H -#include - #define GPMC_BUF_EMPTY 0 #define GPMC_BUF_FULL 1 -- 2.25.1
