From 05e152c76a1efaa3165afecf5acf535c8283f386 Mon Sep 17 00:00:00 2001 From: R Sricharan Date: Tue, 5 Jun 2012 16:21:32 +0530 Subject: ARM: OMAP5: Add minimal support for OMAP5430 SOC OMAP5430 is Texas Instrument's SOC based on ARM Cortex-A15 SMP architecture. It's a dual core SOC with GIC used for interrupt handling and with an integrated L2 cache controller. OMAP5432 is another variant of OMAP5430, with a memory controller supporting DDR3 and SATA. Patch includes: - The machine specific headers and sources updates. - Platform header updates. - Minimum initialisation support for serial. - IO table init Signed-off-by: R Sricharan Signed-off-by: Santosh Shilimkar --- arch/arm/plat-omap/sram.c | 11 +++++++++-- 1 file changed, 9 insertions(+), 2 deletions(-) (limited to 'arch/arm/plat-omap/sram.c') diff --git a/arch/arm/plat-omap/sram.c b/arch/arm/plat-omap/sram.c index 70cf825bdd8..766181cb5c9 100644 --- a/arch/arm/plat-omap/sram.c +++ b/arch/arm/plat-omap/sram.c @@ -6,8 +6,8 @@ * Copyright (C) 2005 Nokia Corporation * Written by Tony Lindgren * - * Copyright (C) 2009 Texas Instruments - * Added OMAP4 support - Santosh Shilimkar + * Copyright (C) 2009-2012 Texas Instruments + * Added OMAP4/5 support - Santosh Shilimkar * * This program is free software; you can redistribute it and/or modify * it under the terms of the GNU General Public License version 2 as @@ -44,6 +44,7 @@ #else #define OMAP4_SRAM_PUB_PA (OMAP4_SRAM_PA + 0x4000) #endif +#define OMAP5_SRAM_PA 0x40300000 #if defined(CONFIG_ARCH_OMAP2PLUS) #define SRAM_BOOTLOADER_SZ 0x00 @@ -118,6 +119,9 @@ static void __init omap_detect_sram(void) } else if (cpu_is_omap44xx()) { omap_sram_start = OMAP4_SRAM_PUB_PA; omap_sram_size = 0xa000; /* 40K */ + } else if (soc_is_omap54xx()) { + omap_sram_start = OMAP5_SRAM_PA; + omap_sram_size = SZ_128K; /* 128KB */ } else { omap_sram_start = OMAP2_SRAM_PUB_PA; omap_sram_size = 0x800; /* 2K */ @@ -132,6 +136,9 @@ static void __init omap_detect_sram(void) } else if (cpu_is_omap44xx()) { omap_sram_start = OMAP4_SRAM_PA; omap_sram_size = 0xe000; /* 56K */ + } else if (soc_is_omap54xx()) { + omap_sram_start = OMAP5_SRAM_PA; + omap_sram_size = SZ_128K; /* 128KB */ } else { omap_sram_start = OMAP2_SRAM_PA; if (cpu_is_omap242x()) -- cgit v1.2.2
