[PATCHv2 2/3] qemu: format SLIC ACPI table command line

[Ján Tomko <jtomko@xxxxxxxxxx>]

<os>
  <acpi>
    <table type="slic">/path/to/acpi/table/file</table>
  </acpi>
</os>

will result in:

-acpitable sig=SLIC,file=/path/to/acpi/table/file

This option was introduced by QEMU commit 8a92ea2 in 2009.
