[edk2-devel] [PATCH edk2-platforms v2 0/8] RPi: Drop EmbeddedPkg reset runtime

["Ard Biesheuvel via groups.io" <ardb+git=google.com@groups.io>]

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
