How to pass data from UBoot to UEFI

Question

Hello, we use Windows 10 IoT with some of our boards equipped with imx8mp. It works fine so far. In our production line we can easily automatic configure UBoot environment with special data (like Network Address, board name, HW revision and so on). Is there an easy way to pass (this) data from UBoot to UEFI while launch it? We don’t want to use an EPROM or similar. Many thanks Christian
