Macros
#define	DT_MEM_ARM64_MASK   DT_MEM_ARCH_ATTR_MASK
	Mask for ARM64 architecture-specific memory attribute bits.
#define	DT_MEM_ARM64_GET(x)
	Extract ARM64-specific bits from a DT memory attribute value.
#define	DT_MEM_ARM64(x)
	Shift a raw ARM64 attribute into the architecture field.
#define	ATTR_ARM64_CACHE_WB   BIT(1)
	Write-Back cache policy (only meaningful with DT_MEM_CACHEABLE).

	Normal write-through cacheable memory.
#define	DT_MEM_ARM64_MMU_NORMAL
	Normal write-back cacheable memory.
#define	DT_MEM_ARM64_MMU_UNKNOWN   DT_MEM_ARCH_ATTR_UNKNOWN
	DT value for unknown or unsupported memory type.
