[U-Boot] integratorcp board - multiple definition of `__udivsi3' & undefined reference to `raise' Error

[Gururaja Hebbar K R]

Hi,

I am using CodeSourcery Arm Toolchain to compile U-boot-1.3.3 for integrator cp 
board. 

1. I set the proper environment variables (BUILD_DIR, PATH, CROSS_COMPILE) 

export PATH=/home/user/project/arm-2007q1/bin:$PATH
export CROSS_COMPILE=arm-none-linux-gnueabi-
export BUILD_DIR=/home/user/project/u_boot/Ubuild_all

2. Then i give 
make clean
make distclean
make cp926ejs_config
make

At the end of the compile i get

make: *** [/home/user/project/u_boot/Ubuild_all/u-boot] Error 1

When i searched for the place of error, i found that in 
uboot-1.3.3/board/integratorcp/integratorcp.c 

@line 235, in function 
ulong get_timer_masked (void)
{
        ..snip..
        ..snip..

        lastdec   = now;
        timestamp = (ulong)(total_count/div_timer);

        return timestamp;
}

I think we need to change it to use do_div function as below.

ulong get_timer_masked (void)
{
        unsigned long long n;

        ..snip..
        ..snip..
        lastdec = now;

        n = total_count;
        do_div(n, div_timer);
        timestamp = (ulong)n;
        
        return timestamp;
}

Also include div64.h

If this correct, then i can send a patch for integrator[ap/cp] board. Since 
both has same c code for this function.

Correct me if i am wrong

Thanks in advance

Gururaja
