[edk2-devel] [PATCH v5 0/7] get rid of DeviceTree from SbsaQemu

[Xiong Yining]

Many thanks to Marcin Juszkiewicz for his previous work on get rid of DeviceTree from 
SbsaQemu https://openfw.io/edk2-devel/20240124-no-dt-for-cpu-v3-0-5375fcf09037@linaro.org/.

To stop the use of DeviceTree on the EDK2 , we add the support for getting the memory 
information via SMC calls based on his patch.

TF-A part: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/25891.

To be compatible with old TF-A, if the SMC calls failed, we can pase DeviceTree data
directly.

Changes in v4:
-patch 6 add the support for getting the hardware information of memory via SMC calls.
-patch 7 add the fallbacks of DeviceTree when SMC calls defined on patch 6 failled.
-replace FdtHelperGetMpidr() with SbsaQemuGetMpidr() on patch 4 to compile successfully.

Changes in v5:
-add the patch "Platform/SbsaQemu: add SbsaQemuHardwareInfoLib" provided by Marcin Juszkiewicz.

Marcin Juszkiewicz (5):
  Platform/SbsaQemu: add SbsaQemuHardwareInfoLib
  Platform/SbsaQemu: read amount of cpus during init
  Platform/SbsaQemu: use PcdCoreCount directly
  Platform/SbsaQemu: move FdtHandlerLib to SbsaQemuHardwareInfoLib
  Platform/SbsaQemu: hang if there is no cpu information

Xiong Yining (2):
  Platform/SbsaQemu: get the information of memory via SMC calls
  Platform/SbsaQemu: add DeviceTree fallbacks to parse memory
    information
