you are right I was in the mid of a change to resize partitions. Now 
the dts looks like:

barebox: partition at 0 {
    label = "barebox";
    reg = <0x0 0x0200000>;
};

barebox_env: partition at 200000 {
    label = "barebox-env";
    reg = <0x0200000 0x040000>;
};

barebox_state: partition at 240000 {
    label = "barebox-state";
    reg = <0x0240000 0x040000>;
};

unfortunately devinfo reports the same information on both v2025.01.0 
and v2025.07.0

`-- 2008000.spi at 2008000.of
   `-- flash at 00
	  `-- nor0
		 `-- 0x00000000-0x00ffffff (    16 MiB): /dev/nor0
		 `-- nor0.barebox
			`-- 0x00000000-0x001fffff (     2 MiB): /dev/nor0.barebox
		 `-- nor0.barebox-env
			`-- 0x00000000-0x0003ffff (   256 KiB): /dev/nor0.barebox-env
		 `-- nor0.barebox-state
			`-- 0x00000000-0x0003ffff (   256 KiB): /dev/nor0.barebox-state


On v2025.07.0 every time I write barebox-env part (e.g. with nv 
command) also barebox
part is written. This on v2025.01.0 does not happen.

I supposed the problem was in the fixed-partition bindings but maybe it 
is somewhere
else, for example in the spinor driver.

Is that something I may test to understand more?

Best,
Stefano
