This entire RFC series is the first stab at making SoCFPGA usable with mainline U-Boot again. There are still some bits missing, but in general, this allows me to use mainline U-Boot on my SoCFPGA systems. The big missing part is the SPL generation, which still needs a lot of additional work.
This set contains patches for a few subsystems, bu the most part is the SoCFPGA chip support.
Most of the patches should be in good shape already, so I wonder if the RFC tag is really necessary.
Just... I earlier today I tested Marek's git tree based on this series, and it works well for me on board similar to sockit.
So

Thanks and best regards,
PavelI applied all the patches to v2014.10-rc2, and I see that the watchdog has been enabled and it's getting reset:

This doesn't seem like a WDT problem. How much DRAM is there on that kit ? In any case, try this:
- Edit arch/arm/cpu/armv7/socfpga/misc.c
- Locate call to get_ram_size()
- Replace this function call with the size of your DRAM in bytes. (that is, make it "gd->ram_size = 128 * 1024 * 1024;" if you have 128MiB)
I suspect get_ram_size() on socfpga is still broken in mainline and causes this crash you observe.
btw you don't happen to have a spare CV and AV kits you could send me, so I can do the testing rounds on them too, do you ?
What board are doing your testing on? The Arrow Sockit?
I also see this error print:

Do you see this on your side? I can track it down...
Thanks, Dinh
