Hi Henrik,

I took a quick look at your patches...

I think you should add README file in doc directory. It should at least contain information how to add support for new boards and point to the tool used for generating images.

Do you have any plans for adding support so the boards can boot from SPI/NAND/NOR, anything else then MMC/SD ?

Luka

Thanks for your patch reviews. Will fix up your comments and submit a new batch of patches later tonight.

There have long been thougts about moving the SPL DRAM controller parameters to a boot header added by mksunxiboot instead of wiring them into the source.

Which tool for generating images? mksunxiboot? The SPL image is built automatically.

But yes, a README explaining how to install the SPL would help. We do have a bit of a such README but I see now that it's slightly misplaced as tools/mksunxiboot.README, should move do doc/README.sunxi and expanded a bit.

NAND is coming once we get the NAND controller under reasonable control. It's a little too smart controller to fit nicely in mtd, and not exactly well documented. Plus that many boards are using NAND chips not recognised by u-boot mtd code.

Support for booting from MMC2 is also coming.

There is no known boards using SPI boot media so this probably will not get added in the near future.

NOR is not supported by the SoC other than in SPI package.

Regards
Henrik

You might want to wait a few days... Somebody else might have comments.

Ah ok, I missed that. So the generated SPL image just needs to be copied on the card ? If yes please put that into README in doc directory.

We should have a short tools/mksunxiboot.README too, so don't delete that one.

Ok. Booting from NAND is something I would like to have ;)

Ok. Thanks for the information.

Good point. Will resuimt the patchset with accumulated fixes by next weekend.

Dear Henrik Nordstr?m,

[...]

The mkimage infrastructure won't work? I think it's much better than yet another tool (mksunxi...)

Best regards,
Marek Vasut

Suggestion how to fit adding an SPL header with these parameters in mkimage is welcome

Got sent a bit premature.

Have not spent time in integrating this header mkimage because the tool is currently only used build-time. There is at this time no need to have a tool for adding this header outside of running make.

If the SPL parameters are "runtime" parameterized instead of wired into C code then it makes great sense to add this to mkimage. Just not entirely sure on what the proper usage parameters of mkimage is to supply the needed SPL parameters. Or where to keep those parameters in the tree if not in the source.

Henrik

Hi Henrik,

Thanks for your hard work - I did promise to help you through the patch submission process, but unfortunately a few personal issues took precedence.

It's good to see not only the core A10 support, but several boards right off the bat. With respect to the boards, is putting them all in the same board directory the right thing to do? The are each manufactured by different vendors, and as far as I can tell the board directory follows a style more like /board/<vendor>/<model> (or /board/<model> for vendors with only one board)

As Wolfgang mentioned, don't forget to run your patches through checkpatch.pl and make sure you properly prefix your next version v2

Regards,

Graeme

I don't know. Stefan suggested the current layout in lack of anthing that really is board unique.

These boards do not really have anything unique as far as main u-boot is concerned. They only differ in the DRAM parameters needed by SPL.

I thought I had fixed all checkpatch things that matters, but obviously missed some.

And better to get the patches looked at. Did not expect them to pass without comments.

Regards
Henrik
