PS13, Line 78: 	const char *description;
Maybe add a bool need_soc_fixup field and set the field in sa_mem_map_descriptor init (e.g. https://review.coreboot.org/c/coreboot/+/83318/13/src/soc/intel/common/block...) using a Kconfig item. The Kconfig item could be default as false but could be redefined in SoC kconfig to true.

At register accessing codes, when need_soc_fixup is true, to invoke the soc_fixup function there (no need to use weak declaration due to compiler optimization).
