/**
 * DOC: WMI event receiving - theory of operations
 *
 * When firmware about to report WMI event, it fills memory area
 * in the mailbox and raises misc. IRQ. Thread interrupt handler invoked for
 * the misc IRQ, function @wmi_recv_cmd called by thread IRQ handler.
 *
 * @wmi_recv_cmd reads event, allocates memory chunk  and attaches it to the
 * event list @wil->pending_wmi_ev. Then, work queue @wil->wmi_wq wakes up
 * and handles events within the @wmi_event_worker. Every event get detached
 * from list, processed and deleted.
 *
 * Purpose for this mechanism is to release IRQ thread; otherwise,
 * if WMI event handling involves another WMI command flow, this 2-nd flow
 * won't be completed because of blocked IRQ thread.
 */

/**
 * DOC: Addressing - theory of operations
 *
 * There are several buses present on the WIL6210 card.
 * Same memory areas are visible at different address on
 * the different busses. There are 3 main bus masters:
 *  - MAC CPU (ucode)
 *  - User CPU (firmware)
 *  - AHB (host)
 *
 * On the PCI bus, there is one BAR (BAR0) of 2Mb size, exposing
 * AHB addresses starting from 0x880000
 *
 * Internally, firmware uses addresses that allow faster access but
 * are invisible from the host. To read from these addresses, alternative
 * AHB address must be used.
