fixed partitions issue

[Stefano Manni <stefano.manni@gmail.com>]

Dear all,

I'm encountering an issue with fixed-partitions on spinor with 
v2025.07.0 that
was not there in v2025.01.0.

The partitions are configured as follows:

 partitions {
     compatible = "fixed-partitions";
     #size-cells = <1>;
     #address-cells = <1>;

     barebox: partition@0 {
         label = "barebox";
         reg = <0x0 0x0100000>;
     };

     barebox_env: partition@100000 {
         label = "barebox-env";
         reg = <0x0100000 0x100000>;
     };

     barebox_state: partition@200000 {
         label = "barebox-state";
         reg = <0x0100000 0x100000>;
     };
 };

It seems to me the partition offsets (0, 0x100000, 0x200000) are not 
taken into account
so the results is that all the partitions point to the same piece of 
memory. That's how I tested it:

Do you have any hint? After the changes on drivers/of/partition.c 
between v2025.01.0 and v2025.07.0
shall I need to change something in my dts?

Best,
