     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.

     52 * DOC: Addressing - theory of operations

     54 * There are several buses present on the WIL6210 card.
     55 * Same memory areas are visible at different address on
     56 * the different busses. There are 3 main bus masters:
     57 *  - MAC CPU (ucode)
     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.
