[edk2-devel] [PATCH edk2-platforms v2 0/3] SbsaQemu: Align the PPTT tables with QEMU

["Marcin Juszkiewicz" <marcin.juszkiewicz@linaro.org>]

We want to make sure that CPU topology information given to QEMU would
be provided to the operating system. So we use SMC call to ask TF-A for
amount of sockets, clusters, cores and threads set in QEMU config.

The TF-A part is already merged:

Changes since v1 (Marcin Juszkiewicz):
- use ACPI 6.5 structures (instead of 6.3)
- add patch to move cache data to cores (instead of clusters)
  - this is for future MPAM support
- reformatted sources using uncrustify
- changed debug output to allow singular values (s/are/:/)

      Platform/SbsaQemu: get the information of CPU topology via SMC calls
      SbsaQemu: provide cache info per core in PPTT
