Re: [Linaro-uefi] [PATCH edk2-platforms v1 19/38] Hisilicon/Hi1620: Add ACPI PPTT table

This driver fetches information from MADT, so it is adaptable for partial good and 1P/2P, since MADT is updated for different configurations by certain mechanism.

Since L2 cache is also private resource of core, so we need to set the next level of cache for L1I and L1D, which is important for OS to parse cache hierarchy.

It's a bit silly that we don't have any structure definition for MPIDR. If you feel you have the time, please submit a patch to ArmPkg/Include/Guid/ArmMpCoreInfo.h, adding one. Or maybe two - one for the _UP variant and one for the _MP variant. If you don't have the time, just a note to the universe that we should do this.
