[U-Boot] [PATCH] arm: sunxi: Add icnova-a20-swac defconfig and dts file

The ICnova-A20-SWAC is a baseboard, equipped with the ICnova-A20 SoM from In-Circuit:
http://wiki.in-circuit.de/index.php5?title=ICnova_A20_SODIMM http://linux-sunxi.org/In-Circuit_ICnova_A20
This patch adds support for this board, including ethernet, LCD and USB support.

Yes. The name of the DT especially doesn't really make sense. The "SWAC" name isn't referenced anywhere, the module cannot be used alone, and there's a single combination available (A20 SODIMM + ADB4006)

At least one other combination is available. A custom board from SWAC equipped with the SoM. What is the preferred method to support SoM's with multiple baseboards? Something like:
sun7i-a20-icnova.dtsi sun7i-a20-icnova-adb4006.dts sun7i-a20-icnova-swac.dts

Okay. Hans, do you want me to change this (and potential other changes as well - see file naming above) via a follow-up patch once its available in mainline U-Boot?
Thanks, Stefan

Yes. The name of the DT especially doesn't really make sense. The "SWAC" name isn't referenced anywhere, the module cannot be used alone, and there's a single combination available (A20 SODIMM + ADB4006)
At least one other combination is available. A custom board from SWAC equipped with the SoM. What is the preferred method to support SoM's with multiple baseboards? Something like:

Okay. Hans, do you want me to change this (and potential other changes as well - see file naming above) via a follow-up patch once its available in mainline U-Boot?
Actually I would prefer to get this right in one go, esp. the filename bits, having u-boot and the kernel disagreeing on the dtb filename is no good. So I plan to remove this version of the patch from u-boot-sunxi/next for now. Once you and Maxime agree on a dts / dtb filename please submit a new version and I'll merge that one instead.
Regards,
Hans

Wasn't our policy supposed to be that we (u-boot) would only take DTS files which were at least on their way to mainline Linux (i.e. in Maxime's tree)?

Ah, my bad then. I was under the impression that you were adding support for the SoM + ADB4006. Sorry.

Yep, that would make much more sense. I have an ADB4006 here, so I can do that one if you want, but we should totally split the common part in a DTSI.

No problem.
What is the preferred method to support SoM's with multiple baseboards? Something like:

Yep, that would make much more sense. I have an ADB4006 here, so I can do that one if you want, but we should totally split the common part in a DTSI.
Okay. I'll try to find some time tomorrow to split this and send you a first version for Linux this time. Since I don't have the ADB4006 baseboard it would be great if you could step in here.
Thanks, Stefan

Users are free to choose this, they can always enable this themselves after running make foo_defconfig.
As for why not give the MAINTAINERS a choice on this, as said I believe that we should not shipp defconfigs with this set by default as part of mainline u-boot. The reasons for this are:
1) It is inconsistent with what we are doing for all other sunxi boards where we are primarily targetting mainline
2) It communicates that CONFIG_OLD_SUNXI_KERNEL_COMPAT is an officially supported end-user feature, where as in reality it is targeted at developers who need to run an old sunxi kernel every now and then to see how that kernel exactly programs certain registers, etc.
3) It means we ship with a severely crippled defconfig for mainline kernel users, mainline users will loose both smp and hyp mode support on the A20 when this option is set.
I'm sorry but I'm not going to budge on this one, having CONFIG_OLD_SUNXI_KERNEL_COMPAT=y in a defconfig is simply not acceptable IMHO. It is not a board specific thing, and there are very good reasons why it defaults to n in board/sunxi/Kconfig
