[ELDK] U-Boot version required to boot kernel 3.10 on PowerPC

I went back to the kernel sources that were used to build our legacy 2.6.38 and indeed there is a proprietary BSP source file which I merged into a vanilla 2.6.38 tree and now it works. From here I can start bisecting with increasing kernel versions.

Thank you for your support everybody,

I totally agree :)
