Huashan Pi board is an embedded development platform based on the

Currently, it can boot to a basic shell.

Applied to riscv-dt-for-next, thanks! LMK if something looks not as
expected.

Thanks for the confirmation. But I suggest to revert these patches.
Several days ago, Sophgo informed me that CV1810 series will be
renamed. And the Huashan Pi will switch to the chip with new name.
To avoid unnecessary conflict, please drop these patch and I will
prepare a new patch once the renamed chip is launched.
This is a board that exists, that you (and possibly others) have, right?
Yes, of course.
I dunno then. It sounds from your message that this is purely a rebrand
of the SoCs,
IIRC, it is.
FYI, Chen and Chao. Maybe you know something more.
so since people already have these boards, I'd rather not.
We should be able to support both since it's just a naming change,
right?
I agree with this. If the above is true, we can just reuse the exists code
with a different compatible name, right?
I think so? I'm not sure what the precedent really is for pure
rebrandings of an SoC.
I say for now, assume we can do that, and we can discuss it with Rob and
Krzysztof when the time comes if there is no difference between the SoCs
and boards.
Cheers,
Conor.
As far as I know, sophgo's SoC product names all start with "sg", while
products starting with "cv" come from CVITEK (another chip company).
CVITEK was acquired by sophgo a year ago, so now many SOC product names
that originally started with "cv" are being repackaged and changed to
start with "sg".
For the cv1800b adopted by Duo, Sophgo has made it clear that it will
not change its codename.
But I heard that for other products, such as the cv1812h used by
Huashanpi, sophgo may change their names in the future, but sophgo has
not officially confirmed it yet. Looks like sophgo themselves are still
in the process of digesting cv's products, ;)
Since we have just started to support cv1812h and have not done much
work yet, I suggest not to merge this patch into the mainline, and wait
until there is clear news before doing this to avoid introducing
unnecessary modifications later.
Thanks,
Chen
