Change NV license for dce headers to MIT license as those can be distributed with other linux sources but they are also used in DCE firmware.

/*
|
|
* Defines the various bootstrap commands to DCE.
|
|
*
|
|
* These commands are relatively simple and are mainly used to
|
|
* communicate with DCE during initialization.
|
|
*
|
|
* The fundamental layout of a command is:
|
|
* Bit(s) Field Description
|
|
* 31:31 GO Signals to the DCE that a command is to be
|
|
* processed
|
|
* 30:27 COMMAND Identifies the command that the DCE is to
|
|
* process
|
|
* 26 RESERVED should be 0
|
|
* 25 HILO 0 = PARM is 19:0 of address
|
|
* 1 = PARM is 39:20 of address
|
|
* 24 RDWR 0 = read header
|
|
* 1 = write header
|
|
* 23:20 RESERVED should be 0
|
|
* 19:0 PARM Parameter to the command
|
|
*
|
|
* Once the command has been processed and the CCPLEX receives an interrupt
|
|
* from DCE, the mailbox used will contain any information about the result
|
|
* of the command.
|
|
*
|
|
* The commands are:
|
|
*
|
|
* DCE_BOOT_CMD_VERSION returns the version of the interface
|
|
* DCE_BOOT_CMD_SET_SID sets the SID for a buffer
|
|
* DCE_BOOT_CMD_CHANNEL_INIT initialize an IVC channel
|
|
* DCE_BOOT_CMD_SET_ADDR set the channel address
|
|
* DCE_BOOT_CMD_GET_FSIZE get the size of the frame
|
|
* DCE_BOOT_CMD_SET_NFRAMES set the number of frames
|
|
* DCE_BOOT_CMD_RESET causes DCE to reset to its initial state.
|
|
* This does not cause DCE to reboot. It mearly
|
|
* indicates that all of memory buffers for IPC
|
|
* will be ignored and the CCPLEX will have to
|
|
* re-establish the memory again.
|
|
*
|
|
* DCE_BOOT_CMD_LOCK locks the admin command interface. Requires
|
|
* a full reset of DCE to unlock.
