Subject: Re: [PATCH v1] mtd: rawnand: meson: fix ready/busy command

Hello Miquel!

I exclude this patch from the recent Meson patchset, as it is fix and not related to another patches.
Also I think that I can split Meson patchset (from links below) in the following way:
1) Patch/patchset for OOB layout
2) Patchset for "nand-rb" logic (meson_nand.c + DT bindings)
These two can also go independently:
3) https://lore.kernel.org/linux-mtd/20230601061850.3907800-6-AVKrasnov@sberdevices.ru/
4) https://lore.kernel.org/linux-mtd/20230601061850.3907800-7-AVKrasnov@sberdevices.ru/

What do You think?

Thanks, Arseniy
