[U-Boot] Ask a question about compiler with u-boot?

[peter meng]

Hi,

I met a problem that can not use 'bl' instruction invoke the function that implemented it in another file(use assemble or C language)  with s3c2412 .
But if i put all function in one file , everything is ok .So i want to know what happens here .

Hope get your help about this problem ?

Thanks advanced .
Best Regards.
