The series comes from my commit in U-boot
d64b9cdcd4 ("fdt: translate address if #size-cells = <0>")
and from the subsequent exchange of emails at the end of which I was
suggested to send the patch to the linux kernel
(https://patchwork.ozlabs.org/project/uboot/patch/1614324949-61314-1-git-send-email-bmeng.cn@gmail.com/).

It's 'ranges' that determines translatable which is missing from the
DT. This should have not had a 0 size either though maybe we could
support that.

I have replied to the email you sent to the u-boot mailing list

Does the DT have to be updated anyways for your spread spectrum support?

The spread spectrum support patch does not need this patch to work. They belong 
to two different series.

The second patch of the series aims to demonstrate that the first one, which
enables the translation of addresses also for crossings of DT nodes
with #size-cells = <0>, it really works.

I don't seem to have the 2nd patch... In any case, you should handle
the special case for this platform in code for the platform.

the 2nd patch:
