/**
 * cvmx_stx#_int_reg
 *
 * Notes:
 * * CALPAR0
 *   This bit indicates that the Spi4 calendar table encountered a parity
 *   error on bank0 of the calendar table memory.  This error bit is
 *   associated with the calendar table on the TX interface - the interface
 *   that drives the Spi databus.  The calendar table is used in Spi4 mode
 *   when using the status channel.  Parity errors can occur during normal
 *   operation when the calendar table is constantly being read for the port
 *   information, or during initialization time, when the user has access.
 *   This errors will force the the status channel to the reset state and
 *   begin driving training sequences.  The status channel will also reset.
 *   Software must follow the init sequence to resynch the interface.  This
 *   includes toggling INF_EN which will cancel all outstanding accumulated
 *   credits.
 *
 * * CALPAR1
 *   Identical to CALPAR0 except that it indicates that the error occured
 *   on bank1 (instead of bank0).
 *
 * * OVRBST
 *   STX can track upto a 512KB data burst.  Any packet larger than that is
 *   illegal and will cause confusion in the STX state machine.  BMI is
 *   responsible for throwing away these out of control packets from the
 *   input and the Execs should never generate them on the output.  This is
 *   a fatal error and should have STX_INT_SYNC[OVRBST] set.
 *
 * * DATOVR
 *   FIFO where the Spi4 data ramps upto its transmit frequency has
 *   overflowed.  This is a fatal error and should have
 *   STX_INT_SYNC[DATOVR] set.
 *
 * * DIPERR
 *   This bit will fire if any DIP2 error is caught by the Spi4 status
 *   channel.
 *
 * * NOSYNC
 *   This bit indicates that the number of consecutive DIP2 errors exceeds
 *   STX_DIP_CNT[MAXDIP] and that the interface should be taken down.  The
 *   datapath will be notified and send continuous training sequences until
 *   software resynchronizes the interface.  This error condition should
 *   have STX_INT_SYNC[NOSYNC] set.
 *
 * * UNXFRM
 *   Unexpected framing data was seen on the status channel.
 *
 * * FRMERR
 *   This bit indicates that the number of consecutive unexpected framing
 *   sequences STX_DIP_CNT[MAXFRM] and that the interface should be taken
 *   down.  The datapath will be notified and send continuous training
 *   sequences until software resynchronizes the interface.  This error
 *   condition should have STX_INT_SYNC[FRMERR] set.
 *
 * * SYNCERR
 *   Indicates that an exception marked in STX_INT_SYNC has occured and the
 *   TX datapath is disabled.  It is recommended that the OVRBST, DATOVR,
 *   NOSYNC, and FRMERR error conditions all have their bits set in the
 *   STX_INT_SYNC register.
