PlatformBdsEnterFrontPage() already implements a keypress wait (for
entering the setup utility at boot) with a nice progress bar, only OVMF
has not been using it.
Removing our custom code and utilizing PlatformBdsEnterFrontPage()'s
builtin wait has the following benefits:
- It simplifies OVMF's BDS code.
- Because now we call PlatformBdsEnterFrontPage() unconditionally, it
actually has a chance to look at the EFI_OS_INDICATIONS_BOOT_TO_FW_UI
bit of the "OsIndications" variable, improving compliance with the UEFI
specification. References:
- https://bugzilla.redhat.com/show_bug.cgi?id=1153927
- http://thread.gmane.org/gmane.comp.bios.tianocore.devel/10487
- The progress bar looks nice. (And it keeps the earlier behavior intact,
when the user presses a key on the TianoCore splash screen.)
In any case, we set the timeout to 0 (which doesn't show the progress
bar and proceeds to the boot options immediately) in order to keep the
boot time down.

The second parameter of said function is "ConnectAllHappened", and if set
to TRUE, the function sets "gConnectAllHappened" to TRUE.
This global variable in turn controls whether Intel BDS code *itself*
calls BdsLibConnectAllDriversToAllControllers() in various places -- if
the indicator is TRUE, then the "connect all" is assumed to have been
performed, and Intel BDS doesn't do it itself.
OVMF should pass TRUE as "ConnectAllHappened", because a few lines before
our call to PlatformBdsEnterFrontPage(), we already connect everything
with BdsLibConnectAll(), which includes the effects of
BdsLibConnectAllDriversToAllControllers():
PlatformBdsPolicyBehavior() [OvmfPkg/Library/PlatformBdsLib/BdsPlatform.c]
BdsLibConnectAll() [IntelFrameworkModulePkg/Library/GenericBdsLib/BdsConnect.c]

The PlatformBdsEnterFrontPage() function's first parameter,
"TimeoutDefault", determines the behavior of the setup utility:
- If (TimeoutDefault == 0), then the usual boot order is to be acted upon
immediately.
- If (TimeoutDefault == 0xFFFF), then the setup utility is entered
unconditionally.
- If (0 < TimeoutDefault && TimeoutDefault < 0xFFFF), then the
PlatformBdsEnterFrontPage() function displays a progress bar, waiting
for TimeoutDefault seconds. If the user presses a key, then the setup
utility is entered, otherwise the normal boot option processing takes
place.
The TimeoutDefault parameter is supposed to be set from
gEfiIntelFrameworkModulePkgTokenSpaceGuid.PcdPlatformBootTimeOut
which has the following (matching) documentation in
"IntelFrameworkModulePkg/IntelFrameworkModulePkg.dec":
The number of seconds that the firmware will wait before initiating the
original default boot selection.
A value of 0 indicates that the default boot selection is to be
initiated immediately on boot.
The value of 0xFFFF then firmware will wait for user input before
booting.
OVMF does this actually -- see the Timeout variable in
PlatformBdsPolicyBehavior() -- but right before calling
PlatformBdsEnterFrontPage(), OVMF hardwires TimeoutDefault to 0xFFFF.
This has been acceptable until now, because OVMF implements its own "wait
for keypress at the splash screen" logic in PlatformBdsPolicyBehavior(),
completely avoiding the progress bar mentioned above. OVMF only calls
PlatformBdsEnterFrontPage() when the user presses a key during its own
"splash screen wait", and *then* it indeed makes sense to enter the setup
utility unconditionally.
However, even that way, the
Timeout = 0xffff;
assignment is superfluous, because 0xFFFF is already the default value of
PcdPlatformBootTimeOut in "IntelFrameworkModulePkg.dec", and OvmfPkg
doesn't override it in its DSC files.
