* 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).

* 0 8 16 24 32

*

|
* 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 0xc0. This corresponds to the
