-/*
- * The BCM2835 SoC contains (at least) two CPUs; the VideoCore (a/k/a "GPU")
- * and the ARM CPU. The ARM CPU is often thought of as the main CPU.
- * However, the VideoCore actually controls the initial SoC boot, and hides
- * much of the hardware behind a protocol. This protocol is transported
- * using the SoC's mailbox hardware module.
- *
- * The mailbox hardware supports passing 32-bit values back and forth.
- * Presumably by software convention of the firmware, the bottom 4 bits of the
- * value are used to indicate a logical channel, and the upper 28 bits are the
- * actual payload. Various channels exist using these simple raw messages. See
- * https://github.com/raspberrypi/firmware/wiki/Mailboxes for a list. As an
- * example, the messages on the power management channel are a bitmask of
- * devices whose power should be enabled.
- *
- * The property mailbox channel passes messages that contain the (16-byte
- * aligned) ARM physical address of a memory buffer. This buffer is passed to
- * the VC for processing, is modified in-place by the VC, and the address then
- * passed back to the ARM CPU as the response mailbox message to indicate
- * request completion. The buffers have a generic and extensible format; each
- * buffer contains a standard header, a list of "tags", and a terminating zero
- * entry. Each tag contains an ID indicating its type, and length fields for
- * generic parsing. With some limitations, an arbitrary set of tags may be
- * combined together into a single message buffer. This file defines structs
- * representing the header and many individual tag layouts and IDs.
