With CONFIG_ROCKCHIP_SPL_BACK_TO_BROM=y, it fails to boot with no output
on the console.

With this change, it builds, but it hangs at boot:
U-Boot SPL 2016.09-rc2+dfsg1-2~20160910~6 (Sep 10 2016 - 18:51:28)
Trying to boot from MMC1
U-Boot 2016.09-rc2+dfsg1-2~20160910~6 (Sep 10 2016 - 18:51:28 +0000)
Model: Firefly-RK3288
DRAM:
This is on a firefly with 2GB of ram. I also have one with 4GB of ram,
hence my interest in this patch series!
live well,
vagrant
