[PATCH v3 0/2] (no cover subject)

[Linus Walleij]

This type of firmware partition appear in some devices in
NAND flash, so we need to be able to tag the partitions
with the appropriate type.

The origin of the "SEAttle iMAge" is unknown.

Please do not add things to the end - it increases conflicts and makes
it difficult to find entries when reading the code. Place it after Renesas.

Does not look like you keep order by unit address (see DTS coding style).

Hi, Zixian,

First, it looks like you forgot to write a subject line for your email.

Second, why is there no description of what was changed in the patch 
set? Maybe it was missed.

Introduction to testing can be used as supplementary information, but it 
should not be the main body of this email.

Not "disable", should be "Remove", and please capitalize the first 
letter of the sentences.

Another relatively important change is about the clock, which you seem 
to have missed.

BTW, I suggest you wait until 6.15-rc1 comes out before submitting the 
next version, because I have already sent a PR to Arnd for Sophgo DTS.

I was intended to avoid duplication with commit msg, but it seems unnecessary.
I will try to write a better cover letter next time. Thanks for your review.
