[U-Boot] [mpc8313] objcopy generates huge binary

[Matthew L. Creech]

Using the latest toolchain from CodeSourcery (4.3-50), I can't seem to
build U-Boot for the MPC8313 ERDB platform.  I've tried this with both
2008.10 and 2009.01-rc1.  Grabbing a fresh copy of U-Boot and doing
"make MPC8313ERDB_33_config && make" seems to work at first, but near
the end when it does:

powerpc-linux-gnu-objcopy --gap-fill=0xff -O binary u-boot u-boot.bin

things freeze as objcopy attempts to create a 4GB "u-boot.bin".  The
output file looks legit until here:

00008950  20 57 61 72 6e 69 6e 67  3a 20 52 54 43 20 6f 73  | Warning: RTC os|

000089a0  ff ff ff ff ff ff ff ff  ff ff ff ff ff ff ff ff  |................|

The file size is 4261653072 bytes - this is 0xFE03AA50, which is
suspiciously close to the base NOR address of 0xFE000000, so I'm
assuming that it's attempting to gap-fill the entire address space for
some reason.  I'm not sure whether the issue lies with U-Boot or with
binutils, though, or how to fix it - any ideas on what's wrong here?

Thanks
