This is addressed in the follow-up commit, can we leave this as-is in this commit?

yeah, the line break before `);` looks really odd.

I use a very stupid trick to minimise diffstat noise when reindenting blocks of code during refactoring: I change the indentation in a separate, reproducible commit, so that the diffstat of the non-reproducible part is much smaller.
I've done this several times when refactoring coreboot code. For example, I wanted to refactor some chipset code, but all mainboards would need to be adapted. I started with CB:46702 CB:46703 CB:46704 CB:46705 to do nearly all changes to mainboard code reproducibly. I also had to make CB:46769 to ensure things would work properly, and CB:46700 did the actual refactoring.
Another example of how I break down refactoring changes to hopefully ease review: CB:49398 changes behavior but is very small, CB:49399 is not reproducible but doesn't change behavior, and CB:49400 is quite large but reproducible.
There's no need to change this commit, it's just that it reminded me of similar situations I've encountered, and I wanted to describe an approach I came up with. However, if you think this idea might make this change easier to review, feel free to use it. 😊

PS2, Line 1769:
I'd normally complain about unrelated whitespace changes (this seems accidental), but addressing this would mean having to manually rebase the follow-up change as well. If you don't mind, I'd appreciate if you could undo this.

Nice to see you here Felix :) All good that was not blocking.
What is your another idea? Maybe that's a good idea? I do various refactorings from time to time.

Thank you so much for testing!! I didn't find ich7 device... you helped me so much!
Patchset:
PS2:
New patcheset is a result of merging with commit 93b01904db607ef8169047e68e376dcda1bd7fbe and fixing some comments. But I want to test it again, at least the init_ich_default path that I can test, to verify that I merged correctly with commit 93b01904db607ef8169047e68e376dcda1bd7fbe. I plan to do this tomorrow and then once it's ready I will resolve all comments.

Hello build bot (Jenkins), Nico Huber, Edward O'Callaghan, Angel Pons, Nikolai Artemiev,
I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/flashrom/+/58735
to look at the new patch set (#2).
Change subject: ichspi: Split very long init function into two
......................................................................
ichspi: Split very long init function into two
ich_init_spi is very long, but logically it can be split. Init
function detects the chipset and then the rest of operations depends
on the chipset.
Init function is more readable now, it consists of only a switch.
Initialisation of hwseq and swseq that used to happen in the
beginning of init function now moved to init_ich_default, because
hwseq and swseq are only used for chipsets served by init_ich_default.

Hello build bot (Jenkins), Nico Huber, Edward O'Callaghan, Angel Pons, Nikolai Artemiev,
I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/flashrom/+/58737
to look at the new patch set (#2).
Change subject: ichspi: Extract initialisation of swseq and hwseq into a function
......................................................................
ichspi: Extract initialisation of swseq and hwseq into a function
Initialisation of swseq_data and hwseq_data gets its own function,
which is called from init_ich_default. This makes init_ich_default
more readable.
This patch also gives a name to (previously anonymous) struct
swseq_data. Its sibling struct hwseq_data already has a name. Structs
need names to be able to declare function parameters.

ichspi: Extract handling programmer param into a function
Extract processing of ich_spi_mode into a separate function which
is called from init_ich_default. This makes init_ich_default more
readable and avoids one local variable.

I'd use SPDX license headers as done for coreboot, this avoids having to deal with copyright years 😄
