All known M1* and M2* devices use an identical SPI NOR flash configuration with a partition containing a non-volatile key:value storage. Use a .dtsi and include it for every device. The nvram partition parameters itself depend on the version of the installed Apple iboot boot loader. m1n1 will fill in the current values provided by Apple's iboot.
