This is an alternate layout used by OpenBMC systems

The division of space is as follows:

 u-boot + env: 0.5MB
 kernel/FIT: 5MB
 rofs: 42.5MB
 rwfs: 16MB

I booted your system in qemu and noticed the kcs driver failed to load:

[    2.717595] ast-kcs-bmc: probe of 1e78902c.kcs failed with error -22
[    2.719104] ast-kcs-bmc: probe of 1e789114.kcs failed with error -22

You need to adjust your system to the v2 bindings, in the same way
this patch did:

https://patchwork.ozlabs.org/project/openbmc/patch/20200930075153.2115-1-aladyshev22@gmail.com/

As I have already merged your patch, I did this for you.

# ls /dev/ipmi-kcs*
/dev/ipmi-kcs3  /dev/ipmi-kcs4

Cheers,

Joel
