[U-Boot] Announcing u-boot with full A31 support
Hi,
After spending a lot of time on this, I'm happy to announce that I now have an upstream u-boot based tree with patches adding A31 dram init and SPL support, allowing one to boot Allwinner A31 boards using just u-boot for all stages of the boot :)
You can find my work on this here: https://github.com/jwrdegoede/u-boot-sunxi/tree/sunxi-wip
Building + install works exactly the same as for the A10 / A13 / A20.
I still need to cleanup the axp221 and p2wi patches a bit, and then I'll post the entire series for review.
Regards,
Hans

Is this the reason why PLL1 configuration is still disabled in the patch set?

No that is another item which I need to fix, basically I need to check if I can re-use the pll1 setting code from sun4i, and if not write new code for sun6i, so the plan for v1 of the patch-set is to not make any pll1 changes for now.
Fixing the pll1 stuff is high on my priority list, but there are only so much hours in day...

Hans

Ok, so I've decided to take a shot at this, and this is fixed now, and I've also done the p2wi driver cleanup I wanted to do, so all that is left now is some cleanup of the axp221 driver, and then I'll post the set for review.
Regards,
Hans
