Users might want to have some parameters that can be set
from UEFI environment. UEFI NVRAM variables provide a way
to achieve this functionality. And they require these vars
to be read from bootloader.
This patch provides a library to get read access to the
UEFI variables stored in NV region. The driver was ported
from MdeModulePkg\Universal\Variable\Pei @ EDKII Open Source.
