I've already attached the defconfig file you should use as a base for
your VoCore2 port in my last mail. Please find it attached again. Other
than that you need to apply all 21 patches of Weijie's latest patchset
and this one:

https://patchwork.ozlabs.org/patch/1215073/

Then start changing the configuration to your needs - port to the VoCore2
with its changes (MMC, SD etc). Most of this can be done by using the
RAM version now (again). There is no additional RAM booting target now
any more. You can use the normal U-Boot image for this now. Please note
the changes TEXT_BASE here. Its now 0x80200000.

HTH.

Thanks,
Stefan
