From: Oleksandr Tyshchenko <oleksandr_tyshchenko@xxxxxxxx> The purpose of this patch is to add a possibility for user to be able to select IOREQ support on Arm (which is disabled by default) with retaining the current behaviour on x86 (is selected by HVM and it's prompt is not visible). Also make the IOREQ be depended on CONFIG_EXPERT on Arm since it is considered as Technological Preview feature and update SUPPORT.md.
