From 5785072b3713bad826a5be8aa0f3e4817e51b121 Mon Sep 17 00:00:00 2001 From: Marc Reilly Date: Fri, 1 Oct 2010 13:40:57 +1000 Subject: imx: Internal boot sources, handle all header offsets Makes the internal boot source configurable. Also changes section names slightly so that .flash_header_0x1000 isn't matched to .flash_header_0x100* etc. Signed-off-by: Marc Reilly Signed-off-by: Sascha Hauer --- arch/arm/mach-imx/Kconfig | 22 +++++++++++++++ arch/arm/mach-imx/include/mach/barebox.lds.h | 12 ++++---- arch/arm/mach-imx/include/mach/imx-flash-header.h | 34 +++++++++++++++++------ 3 files changed, 53 insertions(+), 15 deletions(-) diff --git a/arch/arm/mach-imx/Kconfig b/arch/arm/mach-imx/Kconfig index db9030404e..8a4e1ee268 100644 --- a/arch/arm/mach-imx/Kconfig +++ b/arch/arm/mach-imx/Kconfig @@ -40,6 +40,28 @@ config ARCH_IMX_INTERNAL_BOOT bool "support internal boot mode" depends on ARCH_IMX25 || ARCH_IMX35 +choice + depends on ARCH_IMX_INTERNAL_BOOT + prompt "Internal boot source" + help + Determines the location of the header information for internal boot. + 0x100 for OneNAND + 0x400 for NAND, SD/MMC or Serial ROM + 0x1000 for NOR + +config ARCH_IMX_INTERNAL_BOOT_NAND + default y + bool "NAND, SD/MMC, Serial ROM" + select NAND_IMX_BOOT + +config ARCH_IMX_INTERNAL_BOOT_NOR + bool "NOR" + +config ARCH_IMX_INTERNAL_BOOT_ONENAND + bool "OneNAND" + +endchoice + comment "Freescale i.MX System-on-Chip" choice diff --git a/arch/arm/mach-imx/include/mach/barebox.lds.h b/arch/arm/mach-imx/include/mach/barebox.lds.h index 8e1eccda5b..a2932bd79f 100644 --- a/arch/arm/mach-imx/include/mach/barebox.lds.h +++ b/arch/arm/mach-imx/include/mach/barebox.lds.h @@ -5,13 +5,13 @@ .pre_image : { \ KEEP(*(.flash_header_start*)) \ . = 0x100; \ - KEEP(*(.flash_header_0x100*)) \ - KEEP(*(.dcd_entry_0x100*)) \ - KEEP(*(.image_len_0x100*)) \ + KEEP(*(.flash_header_0x0100*)) \ + KEEP(*(.dcd_entry_0x0100*)) \ + KEEP(*(.image_len_0x0100*)) \ . = 0x400; \ - KEEP(*(.flash_header_0x400*)) \ - KEEP(*(.dcd_entry_0x400*)) \ - KEEP(*(.image_len_0x400*)) \ + KEEP(*(.flash_header_0x0400*)) \ + KEEP(*(.dcd_entry_0x0400*)) \ + KEEP(*(.image_len_0x0400*)) \ . = 0x1000; \ KEEP(*(.flash_header_0x1000*)) \ KEEP(*(.dcd_entry_0x1000*)) \ diff --git a/arch/arm/mach-imx/include/mach/imx-flash-header.h b/arch/arm/mach-imx/include/mach/imx-flash-header.h index 831a3aa1e3..f1054da08f 100644 --- a/arch/arm/mach-imx/include/mach/imx-flash-header.h +++ b/arch/arm/mach-imx/include/mach/imx-flash-header.h @@ -3,17 +3,33 @@ #define __flash_header_start __section(.flash_header_start) -#define __flash_header_0x100 __section(.flash_header_0x100) -#define __dcd_entry_0x100 __section(.dcd_entry_0x100) -#define __image_len_0x100 __section(.image_len_0x100) +#if defined(CONFIG_ARCH_IMX_INTERNAL_BOOT_NOR) + #define __flash_header_section __section(.flash_header_0x1000) + #define __dcd_entry_section __section(.dcd_entry_0x1000) + #define __image_len_section __section(.image_len_0x1000) + #define FLASH_HEADER_OFFSET 0x1000 +#elif defined(CONFIG_ARCH_IMX_INTERNAL_BOOT_ONENAND) + #define __flash_header_section __section(.flash_header_0x0100) + #define __dcd_entry_section __section(.dcd_entry_0x0100) + #define __image_len_section __section(.image_len_0x0100) + #define FLASH_HEADER_OFFSET 0x0100 +#else + #define __flash_header_section __section(.flash_header_0x0400) + #define __dcd_entry_section __section(.dcd_entry_0x0400) + #define __image_len_section __section(.image_len_0x0400) + #define FLASH_HEADER_OFFSET 0x0400 +#endif -#define __flash_header_0x400 __section(.flash_header_0x400) -#define __dcd_entry_0x400 __section(.dcd_entry_0x400) -#define __image_len_0x400 __section(.image_len_0x400) +/* + * NOR is not automatically copied anywhere by the boot ROM + */ +#if defined (CONFIG_ARCH_IMX_INTERNAL_BOOT_NOR) + #define DEST_BASE IMX_CS0_BASE +#else + #define DEST_BASE TEXT_BASE +#endif -#define __flash_header_0x1000 __section(.flash_header_0x1000) -#define __dcd_entry_0x1000 __section(.dcd_entry_0x1000) -#define __image_len_0x1000 __section(.image_len_0x1000) +#define FLASH_HEADER_BASE (DEST_BASE + FLASH_HEADER_OFFSET) struct imx_dcd_entry { unsigned long ptr_type; -- cgit v1.2.3
