46 * WMI event receiving - theory of operations
47 *
48 * When firmware about to report WMI event, it fills memory area
49 * in the mailbox and raises misc. IRQ. Thread interrupt handler invoked for
50 * the misc IRQ, function @wmi_recv_cmd called by thread IRQ handler.
51 *
52 * @wmi_recv_cmd reads event, allocates memory chunk and attaches it to the
53 * event list @wil->pending_wmi_ev. Then, work queue @wil->wmi_wq wakes up
54 * and handles events within the @wmi_event_worker. Every event get detached
55 * from list, processed and deleted.
56 *
57 * Purpose for this mechanism is to release IRQ thread; otherwise,
58 * if WMI event handling involves another WMI command flow, this 2-nd flow
59 * won't be completed because of blocked IRQ thread.

65 * There are several buses present on the WIL6210 card.
66 * Same memory areas are visible at different address on
67 * the different busses. There are 3 main bus masters:
68 * - MAC CPU (ucode)
69 * - User CPU (firmware)
70 * - AHB (host)
71 *
72 * On the PCI bus, there is one BAR (BAR0) of 2Mb size, exposing
73 * AHB addresses starting from 0x880000
74 *
75 * Internally, firmware uses addresses that allow faster access but
76 * are invisible from the host. To read from these addresses, alternative
77 * AHB address must be used.
