You're reading the previous value which either contains a default mapping or has the mapping set by the bootloader, and write it back to the register along with a new mask and the REGEN bit set (which BTW is wrong since you don't mask out other fields before updating them). This confirms that this Core -> FPI address translation exists and has to be set properly, so please stop lying about that.
