Hi, While generating MeeGo u-boot repository for omap4_panda configuration, I ran into a curious issue, I happened to add LDFLAGS=--build-id and it ended up generating a 2.5GB u-boot.bin. digging a little further, I see the linking stage adding --build-id
arm-none-linux-gnueabi-ld --build-id -Bstatic -T u-boot.lds -Ttext 0x9ff00000 $UNDEF_SYM arch/arm/cpu/armv7/start.o --start-group lib/libgeneric.a lib/lzma/liblzma.a lib/lzo/liblzo.a arch/arm/cpu/armv7/libarmv7.a arch/arm/cpu/armv7/omap4/libomap4.a arch/arm/lib/libarm.a fs/cramfs/libcramfs.a fs/fat/libfat.a fs/fdos/libfdos.a fs/jffs2/libjffs2.a fs/reiserfs/libreiserfs.a fs/ext2/libext2fs.a fs/yaffs2/libyaffs2.a fs/ubifs/libubifs.a net/libnet.a disk/libdisk.a drivers/bios_emulator/libatibiosemu.a drivers/block/libblock.a drivers/dma/libdma.a drivers/fpga/libfpga.a drivers/gpio/libgpio.a drivers/hwmon/libhwmon.a drivers/i2c/libi2c.a drivers/input/libinput.a drivers/misc/libmisc.a drivers/mmc/libmmc.a drivers/mtd/libmtd.a drivers/mtd/nand/libnand.a drivers/mtd/onenand/libonenand.a drivers/mtd/ubi/libubi.a drivers/mtd/spi/libspi_flash.a drivers/net/libnet.a drivers/net/phy/libphy.a drivers/pci/libpci.a drivers/pcmcia/libpcmcia.a drivers/power/libpower.a drivers/spi/libspi.a drivers/rtc/librtc.a drivers/serial/libserial.a drivers/twserial/libtws.a drivers/usb/gadget/libusb_gadget.a drivers/usb/host/libusb_host.a drivers/usb/musb/libusb_musb.a drivers/usb/phy/libusb_phy.a drivers/video/libvideo.a drivers/watchdog/libwatchdog.a common/libcommon.a lib/libfdt/libfdt.a api/libapi.a post/libpost.a arch/arm/cpu/armv7/omap-common/libomap-common.a board/ti/panda/libpanda.a --end-group /home/nmenon/Src/opensource/u-boot/arch/arm/lib/eabi_compat.o -L /opt/arm/arm-2010q1/bin/../lib/gcc/arm-none-linux-gnueabi/4.4.1/armv4t -lgcc -Map u-boot.map -o u-boot This results in the following section being added to u-boot
Disassembly of section .note.gnu.build-id:

Disassembly of section .text:
9ff00000 <_start>: 9ff00000: ea000012 b 9ff00050 <reset> <snip>
and that explained my 2.5GB as "arm-none-linux-gnueabi-objcopy --gap-fill=0xff -O binary u-boot u-boot.bin" tried to fill up the 0x0 to 0x9ff00000 with 0xff :)
I am just curious if someone had seen and fixed something like this elsewhere..
