In my case, all the Allwinner hardware that I have is already supported
by the mainline u-boot. Except for the http://linux-sunxi.org/Hyundai_A7
tablet. I could easily contribute support for it to the mainline
u-boot, but I strongly dislike the fact that it is probably a trademark
violating counterfeit product. I surely don't want to be listed as a
maintainer for this thing :-) But if anyone wants to add support for
this tablet under his own name, I'll be happy to provide assistance.
I may even post patches for this tablet *without* my S-o-b.
How about submitting a u-boot defconfig and dts file with a different
name for the board, e.g. Allwinner_M723GDX_defconfig and
sun4i-a10-allwinner-m723gdx.dts ? Then we can point people to this
defconfig in: http://linux-sunxi.org/Hyundai_A7
That's an interesting suggestion. So in other words you suggest to treat
this tablet just like any no-name tablet without identification labels?
Yes.
Furthermore, you suggest to use Allwinner as the dts vendor name.
Yes, because in the dts we must provide a vendor name, we do the
same with e.g. the mk802 which is made by a lot of different vendors, see:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/arch/arm/boot/dts/sun4i-a10-mk802.dts
Which has:
compatible = "allwinner,mk802", "allwinner,sun4i-a10";
For the board compatible. Note that in this case we do not have
allwinner in the dts filename, thinking more about this I think this
probably best to do for the tablet in question too, so name the dts
file: sun4i-a10-m723gdx.dts nad the u-boot defconfig m723dx_defconfig.
And for the board compatible use:
compatible = "allwinner,mk723gdx", "allwinner,sun4i-a10";
I'm not sure if Allwinner would be happy to have such a honour
See above, this would leave allwinner only as the vendor in the
board compatible, where allwinner is already present anyways
since they are the SoC vendor.
but this
is none of my concern as long as everything is done according to the
official linux kernel and/or dts policy. Could you please provide a
reference to the relevant documentation if it exists, or do some work
on making sure that such documentation is created?
I'm afraid that there is no documentation on this specifically, nor
would I know where exactly to document it, but there is a clear
pattern for how to deal with generic boards where we do not have
a clear vendor, and that pattern is that they all do as described
above, so I think that treating your tablet as coming from a generic
vendor and then using the above pattern is a good solution.
Mainlining support for this tablet is not very high in my priority
list. It is basically a junk hardware from a questionable vendor
( http://www.hyundai-digital.cn ), which even does not exist anymore.
I don't know if they were shut down because of the official Hyundai
complaint (searching on google shows a few examples of Hyundai
trademark related lawsuits) or just went out of business because they
were not profitable enough. Still, if there are actual users who are
stuck with this hardware and want to have it mainlined, then we can
see what can be done.
Before you were pointing out that one problem with retiring the old
u-boot branches was that they still support boards mainline u-boot
does not, the only way to fix this is one board at a time.
So if you've some time, please add support for this tablet to
mainline u-boot.
Anyway, this was just one example of the Allwinner based hardware
without mainline U-Boot support. I even did not remember about it
until Olliver brought attention to this topic :-) We are yet to decide
about what to do with the wiki pages for such hardware in order to
make sure that the users do not get confused (this was the
Olliver's intention, right?). And unless there is further feedback
and good constructive suggestions, it looks like the git branches
of the u-boot-sunxi repository are best to be kept as they were.
Hmm, I'm really with Olliver on this one that the time has come
to retire the old u-boot branches.
Lets see which boards are supported by the old u-boot which are
not supported by mainline u-boot :
A10_MID_1GB no one really knows what this is, it seems to come from
the SDK and not a real thing, it has no wiki page

I suggest that we simply forget about the ones without a wiki page, and for the
other we
should probably try to contact the creator of the wiki page.
Olliver do you feel up to contacting these people?

Hans
