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 sto= re
boot system firmware such as eMMC, UFS, and NVMe.

The API for all board, platform, and silicon code to consume the firmware<= br> 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 informatio= n.
In order to abstract the potentially hardware-specific details to determin= e
the boot media (for platforms that support multiple firmware boot media devices), the driver retrieves the boot media information using a new libr= ary
class introduced called FirmwareBootMediaInfoLib. A default instance of th= is
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 mo= st
common scenario and to easily allow a board package to substitute the logi= c
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.
