Hello Sasha,
kernel v6.1.77 introduces a regression, with a boot failure, on i.MX7,
with commit db30f469ae8b ("ARM: dts: imx7s: Fix nand-controller #size-cells").
The issue is known [1][2], changing `#size-cells = <0>` is formally
correct, but do not play well with the firmware that are deployed on
those embedded devices, leading to a boot failure.
A mitigation was implemented in the Linux kernel,
commit 84549c816dc3 ("mtd: parsers: ofpart: add workaround for #size-cells 0")
that was merged into v6.3, the firmware was also fixed, however existing
device using old firmware will not boot anymore if updating to a newer
kernel.
I would ask you to drop such a patch from any stable patches queue and
not backport it to any older kernel.
To fix v6.1.y I see two options:
- backport 84549c816dc3
- revert db30f469ae8b
What do you prefer? Should I send myself a patch?
