[U-Boot] sram overflowed

When I try to boot the 3.6 kernel on my Beaglebone it hangs at "Starting kernel". I read that I should try the latest version of u-boot:

git clone git://arago-project.org/git/projects/u-boot-am33x.git

But I get this when I try to make:

ld: u-boot-spl section `.data' will not fit in region `.sram' ld: region `.sram' overflowed by 163 bytes make[1]: *** [/root/u-boot-am33x/spl/u-boot-spl] Error 1 make[1]: Leaving directory `/root/u-boot-am33x/spl' make: *** [spl/u-boot-spl.bin] Error 2

I read here that I should try removing config options like CONFIG_SPL_YMODEM_SUPPORT:

Can anyone tell me how to do that?
