From mboxrd@z Thu Jan 1 00:00:00 1970 From: Aneesh V Date: Tue, 4 Oct 2011 20:41:06 +0530 Subject: [U-Boot] [PATCH] omap: spl: fix build break due to changes in FAT In-Reply-To: References: Message-ID: <1317741066-31121-1-git-send-email-aneesh@ti.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de From: a0393566local (none) FAT library now uses malloc() and free(). But SPL doesn't have heap until now. Setup a heap in SDRAM to fix this issue. However this increases SPL footprint beyond the available SRAM budget. So, compile out some fancy features in the SDARM init bring back footprint under control CC: Sandeep Paulraj CC: Wolfgang Denk Signed-off-by: Aneesh V --- --- arch/arm/cpu/armv7/omap-common/spl.c | 4 ++++ common/Makefile | 2 +- include/configs/omap4_common.h | 19 +++++++++++-------- 3 files changed, 16 insertions(+), 9 deletions(-) diff --git a/arch/arm/cpu/armv7/omap-common/spl.c b/arch/arm/cpu/armv7/omap-common/spl.c index c76fea6..46a1413 100644 --- a/arch/arm/cpu/armv7/omap-common/spl.c +++ b/arch/arm/cpu/armv7/omap-common/spl.c @@ -35,6 +35,7 @@ #include #include #include +#include DECLARE_GLOBAL_DATA_PTR; @@ -106,6 +107,9 @@ void board_init_r(gd_t *id, ulong dummy) u32 boot_device; debug(">>spl:board_init_r()\n"); + mem_malloc_init(CONFIG_SYS_SPL_MALLOC_START, + CONFIG_SYS_SPL_MALLOC_SIZE); + timer_init(); i2c_init(CONFIG_SYS_I2C_SPEED, CONFIG_SYS_I2C_SLAVE); diff --git a/common/Makefile b/common/Makefile index 2edbd71..b424beb 100644 --- a/common/Makefile +++ b/common/Makefile @@ -29,7 +29,6 @@ LIB = $(obj)libcommon.o ifndef CONFIG_SPL_BUILD COBJS-y += main.o COBJS-y += command.o -COBJS-y += dlmalloc.o COBJS-y += exports.o COBJS-$(CONFIG_SYS_HUSH_PARSER) += hush.o COBJS-y += image.o @@ -176,6 +175,7 @@ COBJS-$(CONFIG_USB_KEYBOARD) += usb_kbd.o endif COBJS-y += console.o +COBJS-y += dlmalloc.o COBJS-y += memsize.o COBJS-y += stdio.o diff --git a/include/configs/omap4_common.h b/include/configs/omap4_common.h index 228eac5..f438fc2 100644 --- a/include/configs/omap4_common.h +++ b/include/configs/omap4_common.h @@ -238,6 +238,7 @@ #endif /* Defines for SDRAM init */ +#define CONFIG_SYS_EMIF_PRECALCULATED_TIMING_REGS #ifndef CONFIG_SYS_EMIF_PRECALCULATED_TIMING_REGS #define CONFIG_SYS_AUTOMATIC_SDRAM_DETECTION #define CONFIG_SYS_DEFAULT_LPDDR2_TIMINGS @@ -251,6 +252,16 @@ #define CONFIG_SPL_BSS_START_ADDR 0x80000000 #define CONFIG_SPL_BSS_MAX_SIZE 0x80000 /* 512 KB */ +/* + * 1MB into the SDRAM to allow for SPL's bss at the beginning of SDRAM + * 64 bytes before this address should be set aside for u-boot.img's + * header.
