Bds will try to automatically create this type boot option
when enumerate.
4. Fixed BlockIo - The boot option only points to a Fixed blockIo device,
like HardDisk.
These device should contain a *fixed* blockIo
protocol in their device handle.
BDS will skip fixed blockIo devices, and NOT
automatically create boot option for them. But BDS
will help to delete those fixed blockIo boot option,
whose description rule conflict with other auto-created
boot options.
5. Non-BlockIo Simplefile - The boot option points to a device whose handle
has SimpleFileSystem Protocol, but has no blockio
protocol. These devices do not offer blockIo
protocol, but BDS still can get the
\EFI\BOOT\boot{machinename}.EFI by SimpleFileSystem
Protocol.
6. File - The boot option points to a file. These boot options are usually
created by user manually or OS loader. BDS will not delete or modify
these boot options.
This function will enumerate all possible boot device in the system, and
automatically create boot options for Network, Shell, Removable BlockIo,
and Non-BlockIo Simplefile devices.
It will only execute once of every boot.
@param BdsBootOptionList The header of the link list which indexed all
current boot options
@retval EFI_SUCCESS Finished all the boot device enumerate and create
the boot option base on that boot device
@retval EFI_OUT_OF_RESOURCES Failed to enumerate the boot device and create the boot option list
