mspi Flash NOR device giving size to the MSPI controller

[FRASTM]

Our stm32 octospi controller requires the size of the device it is talking to

In the configuration where the octo flash NOR mx25lm51245 has a property, this value must be passed ot the Parent instance for its initialization at device init.

&mspi1 {
 compatible = "st,stm32-mspi-controller";
 ...
   mx25lm51245: ospi-nor-flash@90000000 {
  		compatible = "mspi-nor-mx25";
		size = <DT_SIZE_M(64)>; /* in Bytes */
   }
};

What would be the structure to pass the flash_mspi_nor_mx_config.mem_size to the MSPI controller ?
What would hold that value, there is no field in the mspi_dev_cfg or mspi_cfg or mspi_dev_id

Note that The mspi_xip_cfg is probably the best place to hold the size (and base address) from the drivers/flash to the drivers/mspi, but this is coming too late in the system init or not coming at all.
