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.
