From 1d2949aeb3a542ec0fd49c98b54fe5590d8ff238 Mon Sep 17 00:00:00 2001 From: Priyanka Jain Date: Thu, 4 Apr 2013 14:40:32 +0530 Subject: board/bsc9131rdb: Update default boot environment settings BSC9131RDB has 1GB DDR. Out of this, only 880MB is passed on to Linux via bootm_size. Remaining -16MB is reserved for PowerPC-DSP shared control area -128MB is reserved for DSP private area. Also 256MB, out of this 880MB is required for data communication between PowerPC and DSP core. For this bootargs are modified to pass parameter to create 1 hugetlb page of 256MB via default_hugepagesz, hugepagesz and hugepages Signed-off-by: Priyanka Jain Signed-off-by: Andy Fleming --- include/configs/BSC9131RDB.h | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'include/configs/BSC9131RDB.h') diff --git a/include/configs/BSC9131RDB.h b/include/configs/BSC9131RDB.h index 5462670..b5911c6 100644 --- a/include/configs/BSC9131RDB.h +++ b/include/configs/BSC9131RDB.h @@ -442,7 +442,9 @@ extern unsigned long get_sdram_size(void); "fdtfile=bsc9131rdb.dtb\0" \ "bdev=sda1\0" \ "hwconfig=usb1:dr_mode=host,phy_type=ulpi\0" \ - "othbootargs=ramdisk_size=600000 \0" \ + "bootm_size=0x37000000\0" \ + "othbootargs=ramdisk_size=600000 " \ + "default_hugepagesz=256m hugepagesz=256m hugepages=1\0" \ "usbext2boot=setenv bootargs root=/dev/ram rw " \ "console=$consoledev,$baudrate $othbootargs; " \ "usb start;" \ -- cgit v1.1
