Hi u-boot community,

I am trying to port u-boot (release u-boot-2014.04-rc3.tar.bz2) to 
FreeBSD on BeagleBone Black.

In FreeBSD, there is a u-boot loader (named ubldr), which can call 
u-boot API to get fdt (Flat Device Tree) data. Example is:
-- fdt header

I have to comment out below 3 lines, in order to get correct fdt data in 
FreeBSD ubldr from u-boot. Would you please advice what is the best way 
to fix this?

In file common/env_common.c:
const uchar *env_get_addr(int index)
{
//      if (gd->env_valid)
//              return (uchar *)(gd->env_addr + index);
//      else
                 return &default_environment[index];
}

-- 
Thanks,
Xuebing Wang
