- * DOMAIN_IO - domain 2 includes all IO only
- * DOMAIN_USER - domain 1 includes all user memory only
- * DOMAIN_KERNEL - domain 0 includes all kernel memory only
- *
- * The domain numbering depends on whether we support 36 physical
- * address for I/O or not. Addresses above the 32 bit boundary can
- * only be mapped using supersections and supersections can only
- * be set for domain 0. We could just default to DOMAIN_IO as zero,
- * but there may be systems with supersection support and no 36-bit
- * addressing. In such cases, we want to map system memory with
- * supersections to reduce TLB misses and footprint.
- *
- * 36-bit addressing and supersections are only available on
- * CPUs based on ARMv6+ or the Intel XSC3 core.
