ArmVirtPkg/ArmVirtQemu*: enable minimal Status Code Routing in DXE
The EFI_RETURN_STATUS_EXTENDED_DATA feature from PI-1.7
(<https://mantis.uefi.org/mantis/view.php?id=1885>) enables platform code
to learn about boot option failures (loading and launching) via status
codes reported by the UEFI Boot Manager.
In commit 59541d41633c, we removed all status code support from
ArmVirtPkg. Reenable that support now, minimally, just to the extent so we
can benefit from the PI-1.7 feature mentioned above:
(1) Include the ReportStatusCodeRouterRuntimeDxe driver.
This driver produces two protocols, EFI_STATUS_CODE_PROTOCOL and
EFI_RSC_HANDLER_PROTOCOL. The former allows DXE phase modules and
runtime modules to report (produce) status codes. The latter allows
the same types of modules to register callbacks for status code
handling (consumption).
(Handler registration occurs only at boot time. Status codes are
delivered to each handler at runtime as well, unless the handler is
unregistered at ExitBootServices().)
(2) Resolve ReportStatusCodeLib to a non-Null instance, for DXE_DRIVER
modules only. This way DXE_DRIVER modules that use the
REPORT_STATUS_CODE_EX() macro and friends will reach
EFI_STATUS_CODE_PROTOCOL from point (1).
(3) Set PcdReportStatusCodePropertyMask to 3 (the default value is 0).
This causes the REPORT_STATUS_CODE_EX() macro and friends to let
Progress Codes (bit#0) and Error Codes (bit#1) through to point (1).
Debug Codes (bit#2) are filtered out.
(4) Include no driver, for now, that registers any status code handler via
EFI_RSC_HANDLER_PROTOCOL, from point (1). Status codes that reach
ReportStatusCodeRouterRuntimeDxe will be thrown away.
(5) Modify only the ArmVirtQemu* platforms. A status code handler will
be added to "ArmVirtPkg/Library/PlatformBootManagerLib" in the next patch,
and this library instance is not consumed by ArmVirtXen.
