Branch Changes - release/202511

===============================



Breaking Changes-dev

--------------------



- General



  - EDK2 packages that were split into mu_tiano_plus, mu_silicon_intel_tiano, mu_silicon_arm_tiano have been kept in mu_basecore. 

  - mu_tiano_plus, mu_silicon_arm_tiano are deprecated, and projects should be updated to no longer consume them.

  - MSVC AARCH64 build support has been removed. Please use ClangPDB or GCC for AARCH64 compilation.

  - Itanium support cleanup. DXE_SAL_DRIVER is no longer recognized as a keyword by build tools. Remove any usage of this term.

  - ARM support (arm 32) has been removed by EDK2.

  - mu_silicon_intel_tiano only contains IntelSiliconPkg from edk2-platforms.

  - EDK2 is moving towards depreciating TOOL_CHAIN_TAG GCC5, and platforms should start planning on using the GCC replacement. NOTE: This has implications for build overrides from dsc and inf files. 



- MdePkg



  - gEfiEventPostReadyToBootGuid has been dropped in favor of EDK2's gEfiEventAfterReadyToBootGuid. Events should be switched to use gEfiEventAfterReadyToBootGuid.



- MdeModulePkg



  - UgaSupport has been removed from EDK2. This includes PCDs associated with it such as gEfiMdeModulePkgTokenSpaceGuid.PcdConOutUgaSupport

  - UefiDevicePathLibStandaloneMm has been removed by EDK2. Platforms should replace this with instance UefiDevicePathLibBase.

  - UhciPei.inf has been removed by EDK2. Remove any reliance on the driver.

  - PPI gPeiUsbHostControllerPpiGuid has been removed by EDK2. Remove any references to it and associated files. 

  - BaseUefiBootManagerLibNull has been removed. It was intended to speed up CI builds, but never to be used in platforms. Remove references to it.

  - MemoryProtectionSpecialRegionGuid support has been depreciated. Remove any references to the includes.

  - gMemoryProtectionNonstopModeProtocolGuid has been removed. Code relying upon it should be changed to expect a system reboot upon exceptions.

  - BaseUefiBootManagerLibNull instance of UefiBootManagerLib has been dropped.

  - Memory Protection Read Protect on Freed memory has been dropped. The implementation resulted in false reports of issues.

  - gEfiEventPostReadyToBootGuid has been dropped in favor of EDK2's gEfiEventAfterReadyToBootGuid



- StandaloneMmPkg



  - MmCommunicationNotifyDxe.inf has been created by splitting the functionality out of MmCommunicationDxe.inf. Platforms will need to update to include the additional driver.



- UefiCpuPkg



  - AmdSysCallLib has been introduced and dependencies taken. AMD based platform may need to include this additional library class.

  - PcdCpuApWakeupBufferReserved has been removed. WakeupBuffers will be allocated as EfiBootServicesData. Please remove pcds from any components.



- EmbeddedPkg



  - FdtLib has been dropped. Please use the BaseFdtLib from MdePkg. (Will require code to be touched because interfaces are not 1:1 compatible).



- ArmPkg



  - ArmMmuLib has been promoted from ArmPkg into UefiCpuPkg. Please update the paths for instances.

  - gArmTokenSpaceGuid.PcdVFPEnabled has been dropped. New implemenation should not require this. 

  - PcdFdMemoryType has been deprecated. Fd memory will be reported as EfiBootServicesData.



MU Overrides on EDK2

--------------------



- At the start of 202511, mu_basecore contains 307 commits on top of edk2-stable202511. Full MU changes list can be viewed `in the changelog `_.



Platform Integration Reference

------------------------------

Reference platforms which consume release/202511 are available in `mu_tiano_platforms `_.



Please note that this version of EDK2 has specific requirements when it comes to TF-A support. 

Platforms that consume this version of EDK2 must ensure their TF-A `contains this set of patches `_.

Failure to contain the appropriate patches will result in a failure to boot.
