From: Ard Biesheuvel <ardb@kernel.org>
The EmbeddedPkg runtime DXE is being retired in favour of the generic
one in MdeModulePkg which is actually being maintained.
RPi uses this driver and the associated EfiResetSystemLib, of which it
has an implementation with value-add for reset notification. So this
logic needs to be moved elsewhere and hooked up to the generic protocols
that implement the same.
Changes since v1:
- boot tested
- add patch to fix pre-existing issue that causes a crash when DmaLib
attempts to set EFI_MEMORY_XP on allocated buffers
- add a patch to force the correct dispatch order for the varstore
related drivers
- fix line endings

Mark RAM ranges as write/execute protectable in the GCD memory map. This
is needed to avoid issues with NonCoherentDmaLib in EmbeddedPkg, which
will fail if it does not manage to set the EFI_MEMORY_XP attribute on
the allocated DMA buffers.

The VarBlockServiceDxe driver needs to be dispatched before the common
VariableRuntimeDxe, but we are currently relying on FDF order and lack
of transitive dependencies for this, which is fragile, and will break
once we move to the generic reset runtime.
So use the existing helper library for this, which can be plugged into
the generic variable drivers, and force them to depex on a GUID that can
be installed as a NULL protocol in VarBlockServiceDxe.

From: Ard Biesheuvel <ardb@kernel.org>
The DumpVars() routine is called directly and via an event notification
callback, and the latter therefore defines the function's prototype,
even though the arguments are unused.
We will introduce another callback into this logic, but via a reset
notifier, which has yet another prototype. So to keep things tidy, drop
the formal parameters from DumpVars() and invoke it via a helper
function that discards the arguments when called as a event notification
callback. We will do the same for the reset notification once that
functionality gets added.

In addition to setting up the home grown reset notification, register
with the generic EFI protocol that does the same. This event is
triggered from the reset runtime implemented in MdeModulePkg, to which
we will be switching the RPi platforms in a subsequent patch.

To: devel; +Cc: Ard Biesheuvel, Leif Lindholm, Jeremy Linton
From: Ard Biesheuvel <ardb@kernel.org>
Duplicate the logic that is triggered on a system reset into the
platform boot manager driver, and hook it up to the EDK2 platform
specific reset notification driver. This is supported by generic EDK2
code in MdeModulePkg, allowing us to retire the platform-specific
EfiResetSystemLib implementation in a subsequent patch. This is needed
because this library class and its only user ResetRuntimeDxe in
EmbeddedPkg are deprecated and are going to be removed.

From: Ard Biesheuvel <ardb@kernel.org>
Drop the reference to the special reset runtime DXE driver in
EmbeddedPkg, and move to the one in MdeModulePkg shared between all
architectures. This version implements reset notifications, allowing us
to retire the home grown version of that functionality in a subsequent
patch.
Add depexes to the components that rely on the reset notification
protocols to ensure that they are not dispatched before those protocols
are made available by the reset runtime DXE driver.
