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

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