Hi everyone,
This series adds full SPL with DRAM initialization for sun9i (A80).
The bulk of the work was done by the people at Theobroma Systems.
Their work can be found here:
https://git.theobroma-systems.com/armadillo-u-boot.git/
I picked the essential patches and cleaned them up a bit more,
and added commit messages if they were missing.
As the DRAM bits are essentially a code dump with some cleanups and
some bits disabled, expect many warnings. Checkpatch is still not
happy with it.
I've tested the series on both my A80 boards, which I've added
defconfigs for in the last 2 patches. My A80 Optimus does not
boot from micro SD, so I'm still FEL booting that one. But my
Cubieboard 4 is now standalone.
As usual, please have a look, test if possible.
Awesome, thanks for doing this and it was good to have
some face2face time at ELCE.
I've merged this into my personal sunxi-wip u-boot branch,
I've made 2 changes:
1) in : ¨sunxi: DRAM initialisation for sun9i" there are a
lot of #if 0 #endif blocks, most of these document some features
which we may want to enable in the future, but a few were just
dead weight IMHO, so I've pruned a few
Thanks. I suppose some of the testing and verbose debug calls
aren't needed. Most of the #if 0 blocks within data structures
were C99 // comments that I fixed up to get checkpatch happy.
About the features, I was already half way through the clock
code cleanup when Maxime pointed me to Theobroma's repository,
so I could add and test sigma delta modulation for PLL DDR.
If you want to, I would be fine with adding that, but IIRC
we are not doing that on a number of other SoC generations
either, not sure what this would bring it us. So it is up to
you.
For the other types of DRAM we could clean it up, but there's
really no hardware to test it on.
I would not bother with this until someone with the relevant
hardware comes forward.
2) in : "sunxi: Add support for A80 Optimus board", we already
have a configs/Merrii_A80_Optimus_defconfig, so I've made the patch
update that instead of adding a new defconfig
Cool. I didn't notice.
I have not tested this yet, I will do tomorrow, assuming it
works for me too I will include it in my next pull-req (*) and
try to get it included in the 2016.11 release, yes the merge
window has closed, but the changes here are very isolated so
I will try and see what Tom says :)
Do you need me to send a v2 addressing review comments?
No need, I've fixed everything up in my own tree.

Hans
Thanks
