OK, hold up.  We went through this a while back which is why things are
how they are today.  First, we have things setup today such that you can
throw stack (at the point we do env in SPL) into DDR.  This means we can
keep doing things the way they are.  You can take a look at
include/configs/am335x_evm.h and where CONFIG_EMMC_BOOT is set, that's
how we do what it looks like you're trying to do on imx6 but on TI
am335x.
