*** THANKS!! ***
now I need to be able to duplicate this and, if needed, to modify. I tried using last Weijie patch-set, but I got the same error You reported, I "fixed" it removing `obj-y += time.o` from `arch/mips/cpu/Makefile`, but I was afraid to test results ;)
What is the right sequence to get Your results?
Note: I will need to have also working MMC/SD; in stock U-Boot I had to backport some drivers for that; is it supposed to work out-of-the-box (given right config, of course) in this version?
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
