* The client writes its request into MC shared memory , and rings the
* doorbell . Each request is completed either by the MC writing
* back into shared memory , or by writing out an event .
*
* All MCDI commands support completion by shared memory response . Each
* request may also contain additional data ( accounted for by HEADER . LEN ) ,
* and some responses may also contain additional data ( again , accounted
* for by HEADER . LEN ) .
*
* Some MCDI commands support completion by event , in which any associated
* response data is included in the event .
*
* The protocol requires one response to be delivered for every request ; a
* request should not be sent unless the response for the previous request
* has been received ( either by polling shared memory , or by receiving
* an event ) .

* The MC can generate events for two reasons :
* - To advance a shared memory request if XFLAGS_EVREQ was set
* - As a notification ( link state , i2c event ) , controlled
* via MC_CMD_LOG_CTRL
*
* Both events share a common structure :
*
* 0 32 33 36 44 52 60
* | Data | Cont | Level | Src | Code | Rsvd |
* |
* \ There is another event pending in this notification
*

*
* - LEVEL = = INFO Command succeeded
* - LEVEL = = ERR Command failed
*
* 0 8 16 24 32
* | Seq | Datalen | Errno | Rsvd |
*
* These fields are taken directly out of the standard MCDI header , i . e . ,
* LEVEL = = ERR , Datalen = = 0 = > Reboot
*
* Events can be squirted out of the UART ( using LOG_CTRL ) without a
* MCDI header . An event can be distinguished from a MCDI response by
* examining the first byte which is 0 xc0 . This corresponds to the
* non - existent MCDI command MC_CMD_DEBUG_LOG .
*
* 0 7 8
* | command | Resync | = 0 xc0
*
* Since the event is written in big - endian byte order , this works
* providing bits 56 - 63 of the event are 0 xc0 .
*
* 56 60 63
* | Rsvd | Code | = 0 xc0
*
