The MediaInfo structure describes an enumeration of possible block device
types. This enumeration exists because no device paths are actually passed
across interfaces that describe the type or class of hardware that is publishing
the block I/O interface. This enumeration will allow for policy decisions
in the Recovery PEIM, such as "Try to recover from legacy floppy first,
LS-120 second, CD-ROM third." If there are multiple partitions abstracted
by a given device type, they should be reported in ascending order; this
order also applies to nested partitions, such as legacy MBR, where the
outermost partitions would have precedence in the reporting order. The
same logic applies to systems such as IDE that have precedence relationships
like "Master/Slave" or "Primary/Secondary". The master device should be
reported first, the slave second.

Gets a block device's media information.
This function will provide the caller with the specified block device's media
information. If the media changes, calling this function will update the media
information accordingly.
@param[in] PeiServices General-purpose services that are available to every
PEIM
@param[in] This Indicates the EFI_PEI_RECOVERY_BLOCK_IO2_PPI instance.
@param[in] DeviceIndex Specifies the block device to which the function wants
to talk. Because the driver that implements Block I/O
PPIs will manage multiple block devices, the PPIs that
want to talk to a single device must specify the
device index that was assigned during the enumeration
process. This index is a number from one to
NumberBlockDevices.
@param[out] MediaInfo The media information of the specified block media.
The caller is responsible for the ownership of this
data structure.
@par Note:
The MediaInfo structure describes an enumeration of possible block device
types. This enumeration exists because no device paths are actually passed
across interfaces that describe the type or class of hardware that is publishing
the block I/O interface. This enumeration will allow for policy decisions
in the Recovery PEIM, such as "Try to recover from legacy floppy first,
LS-120 second, CD-ROM third." If there are multiple partitions abstracted
by a given device type, they should be reported in ascending order; this
order also applies to nested partitions, such as legacy MBR, where the
outermost partitions would have precedence in the reporting order. The
same logic applies to systems such as IDE that have precedence relationships
like "Master/Slave" or "Primary/Secondary". The master device should be
reported first, the slave second.
@retval EFI_SUCCESS Media information about the specified block device
was obtained successfully.
@retval EFI_DEVICE_ERROR Cannot get the media information due to a hardware
error.
