35  * DOC: WMI event receiving - theory of operations
36  *
37  * When firmware about to report WMI event, it fills memory area
38  * in the mailbox and raises misc. IRQ. Thread interrupt handler invoked for
39  * the misc IRQ, function @wmi_recv_cmd called by thread IRQ handler.
40  *
41  * @wmi_recv_cmd reads event, allocates memory chunk  and attaches it to the
42  * event list @wil->pending_wmi_ev. Then, work queue @wil->wmi_wq wakes up
43  * and handles events within the @wmi_event_worker. Every event get detached
44  * from list, processed and deleted.
45  *
46  * Purpose for this mechanism is to release IRQ thread; otherwise,
47  * if WMI event handling involves another WMI command flow, this 2-nd flow
48  * won't be completed because of blocked IRQ thread.

58  *  - User CPU (firmware)
59  *  - AHB (host)
60  *
61  * On the PCI bus, there is one BAR (BAR0) of 2Mb size, exposing
62  * AHB addresses starting from 0x880000
63  *
64  * Internally, firmware uses addresses that allow faster access but
65  * are invisible from the host. To read from these addresses, alternative
66  * AHB address must be used.
