If uncacheable attribute is included in memory resource HOB, GCD spaces will also have EFI_MEMORY_UC capability, then NonCoherentPciIoAllocateBuffer of NonDiscoverablePciDeviceDxe module will allocate DMA buffer of EFI_MEMORY_UC type, which will cause alignment fault exception with BaseMemoryLibOptDxe.
This not only affects NonDiscoverablePciDeviceDxe, it removes the UC attribute from all DRAM regions in the UEFI memory map, which makes much more sense on ARM
