I am not sure if there is a silicon scope around the FirmwareBootMediaLib. Have
we considered adding this interface to MdePkg, instead?

Subject: [edk2-platforms][PATCH V1 0/3] Add FW Boot Media Device Indicator
This patch series introduces a mechanism for determining the firmware boot
media device. This allows the firmware boot media to be discovered through a
standardized API.
Traditionally, most systems have only supported firmware storage on SPI flash.
Presently, several other storage technologies are being used to store boot
system firmware such as eMMC, UFS, and NVMe.
The API for all board, platform, and silicon code to consume the firmware boot
media device is provided by the FirmwareBootMediaLib in IntelSiliconPkg.
A driver (FirmwareBootMediaInfoPei) is added to BoardModulePkg to serve as a
consistent location for reporting the firmware boot device information. In
order to abstract the potentially hardware-specific details to determine the
boot media (for platforms that support multiple firmware boot media devices),
the driver retrieves the boot media information using a new library class
introduced called FirmwareBootMediaInfoLib. A default instance of this library
class is provided in BoardModulePkg that always returns SPI flash. This is
intended to serve as a default implementation of the library for the most
common scenario and to easily allow a board package to substitute the logic
required to determine the boot media in more complex scenarios. Ultimately,
FirmwareBootMediaInfoPei produces a HOB containing the firmware boot media
device information so it can be used in the HOB consumer phase.
