ACPI global NVS is an area in system memory with various platform defined variables that can be utilized between U-Boot and ACPI ASL codes. U-Boot set these variables at runtime, so that ASL codes can test these variables to provide some runtime flexiblity.
Tested on MinnowMax with CONFIG_INTERNAL_UART set to off, and install a Windows 10, check the internal UART is not exposed in the Windows device manager. This series is available at u-boot-x86/gnvs-working.
