am trying to save NVRAM variables which are modifed in Uefi Payload, but i could not save it.   

what is the role of uefi_nvs.bin file?

coreboot/intel/mainboard/intel/bayleybay_fsp/uefi_nvs.bin

 

Even the boot order does not save into NVRAM variables

Can some one help me on this, Base address is given below 

gEfiMdeModulePkgTokenSpaceGuid.PcdFlashNvStorageVariableBase   | 0xFFF60000

  gEfiMdeModulePkgTokenSpaceGuid.PcdFlashNvStorageFtwWorkingBase | 0xFFF7E000  

  gEfiMdeModulePkgTokenSpaceGuid.PcdFlashNvStorageFtwSpareBase   | 0xFFF80000

In coreboot, i have given the same address

Thanks & Regards
