efi_loader: provide tool to dump SMBIOS table
An EFI binary smbiosdump.efi is provided that can be used to check the
SMBIOS table for consistency and to dump it as a file.
The tool provides the following commands:
check
Check the SMBIOS table for consistency.
exit
Leave the tool.
help
Show available commands.
save
Save the SMBIOS table to a file on the EFI system partition. The file
can be further analyzed with the dmidecode command line tool::
dmidecode --from-dump <filename>
Specifying 'nocolor' as load option data suppresses colored output and
clearing of the screen.
