NRF54L15 ReRAM write-block-size in DTS

[Radoslaw Koppel]

Further into development of the ReRAM file system. I noticed that in generated DTS for nRF54L15 board for the ReRAM we have:

cpuapp_rram: rram@0 {
        compatible = "soc-nv-flash";
        erase-block-size = < 0x1000 >;
        write-block-size = < 0x10 >;
        reg = < 0x0 0x165000 >;
        partitions {
                compatible = "fixed-partitions";
                #address-cells = < 0x1 >;
                #size-cells = < 0x1 >;
                boot_partition: partition@0 {
                        label = "mcuboot";
                        reg = < 0x0 0x10000 >;
                };
                slot0_partition: partition@10000 {
                        label = "image-0";
                        reg = < 0x10000 0x51000 >;
                };
                slot0_ns_partition: partition@61000 {
                        label = "image-0-nonsecure";
                        reg = < 0x61000 0x51000 >;
                };
                slot1_partition: partition@b2000 {
                        label = "image-1";
                        reg = < 0xb2000 0x51000 >;
                };
                slot1_ns_partition: partition@103000 {
                        label = "image-1-nonsecure";
                        reg = < 0x103000 0x51000 >;
                };
                storage_partition: partition@15c000 {
                        label = "storage";
                        reg = < 0x15c000 0x9000 >;
                };
        };
};

What is the reason for providing erase-block-size to the 0x1000 value while the memory does not require erasing? I would expect it to be rather set to the same value like write-block-size. It provides now this value via page layout related functions.
