This library is copied from ArmVirtPkg, in the Arm version, the value of PcdFlashNvStorageVariableBase, PcdFlashNvStorageFtwWorkingBase and PcdFlashNvStorageFtwSpareBase are hardcoded in INC file. This version will calculate them from FDT resource and using the set PCD to store when the NorFlashInitialise is called. By default, the first available flash(not used for storage UEFI code) as NV variable storage medium. In this way, UEFI can better handle the change of flash base address, which is suitable for different cpu architecture board implementation.
