[edk2-devel] [PATCH v2 16/30] ArmVirtPkg: Move PCD of FDT base address and FDT padding to OvmfPkg

["Chao Li" <lichao@loongson.cn>]

Moved PcdDeviceTreeInitialBaseAddress and PcdDeviceTreeAllocationPadding
to OvmfPkg for easier use by other architectures.

Build-tested only (with "ArmVirtQemu.dsc").
