* Device addresses.
*
* Note: for endianness-independence, use 32-bit loads and stores for all
* register accesses to Ethernet, UART and LED devices. Undefined bits
* may need to be masked out if needed when reading if the actual register
* size is smaller than 32 bits.
*
* Note: ML605 bus byte lanes are defined in terms of msbyte and lsbyte
* relative to the processor. So 32-bit registers are accessed consistently
* from both big and little endian processors. However, this means byte
* sequences are not consistent between big and little endian processors.
* This is fine for RAM, and for ROM if ROM is created for a specific
* processor (and thus has correct byte sequences). However this may be
* unexpected for Flash, which might contain a file-system that one wants
* to use for multiple processor configurations (eg. the Flash might contain
* the Ethernet card's address, endianness-independent application data, etc).
* That is, byte sequences written in Flash by a core of a given endianness
* will be byte-swapped when seen by a core of the other endianness.
* Someone implementing an endianness-independent Flash file system will
* likely handle this byte-swapping issue in the Flash driver software.
