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.
