The explanation is in the patch titled
OvmfPkg: introduce gRootBridgesConnectedEventGroupGuid
At this point, this signal doesn't do anything yet.

The ARM RVCT compiler does not allow implicit casts between enumerated
types and integer types. In this particular case, the STUB_FILE::Position
member is overloaded as a KERNEL_BLOB_TYPE identifier, so it does not
hurt to make that cast explicit.

According to the UEFI spec, EFI_EVENT_GROUP_READY_TO_BOOT "is notified by
the system when the Boot Manager is about to load and execute a boot
option". ArmVirtPkg doesn't do this currently when launching a kernel from
the QEMU command line. OvmfPkg does (see git commit 28a34033ee).
At least two edk2-wide callbacks are worth mentioning:
- OnReadyToBoot() in
"MdeModulePkg/Universal/Variable/RuntimeDxe/VariableDxe.c" performs
variable reclaim and (optionally) installs variable usage statistics as
a vendor config table;
- OnReadyToBoot() in
"SecurityPkg/Library/DxeImageVerificationLib/DxeImageVerificationLib.c"
installs the image execution info table if it doesn't exist yet, in
SecureBoot-enabled builds.

Add a fixed pointer PCD to allow build-time selection of VT100 or TTY terminal
type. The default remains VT100 emulation.
Add support for building the ARM QEMU platforms with the TTY terminal
with the "-D TTY_TERMINAL" build option.

Currently, the ArmVirtPkg platforms built with the Intel BDS fail
to signal the end-of-DXE event 'gEfiEndOfDxeEventGroupGuid' when
entering the BDS phase, which results in some loss of functionality,
i.e., variable reclaim in the VariableDxe drivers, and the splitting
of the memory regions that is part of the recently added UEFI 2.5
properties table feature.
As discussed on the edk2-devel mailing list here:
http://thread.gmane.org/gmane.comp.bios.tianocore.devel/16088/focus=16109
it is up to the platform BDS to signal that event, since there may be
platform specific ordering constraints with respect to the signalling
of the event that are difficult to honor at the generic level.
So add the SignalEvent () call to PlatformBdsInit () of ArmVirtPkg's
PlatformBdsLib implementation for the Intel BDS.
