Hi Kurt,

> Thank you for testing the patch. Hmm, are you building with ATF 2.3?

You are right here, I was testing with ATF 2.1, while ATF 2.3 works correctly.
First working commit in ATF is 0aad563c ("rockchip: Update BL31_BASE
to 0x40000").
I suppose, it is worth to mention in the commit message for this
patch. What do you think?

I'm booting from uSD without eMMC installed also.
