- * MEC172x family implements a new Port 0x80 capture block.
- * The BDP HW can capture 8, 16, and 32 bit writes.
- * Interrupt fires when BDP FIFO threshold is reached.
- * Data can be read from a 16-bit register containing:
- * b[7:0] data byte
- * b[9:8] = byte lane
- * b[11:10]= flags indicating current byte is a single byte or part of
- * a multi-byte sequence.
- * b[14:12] = copy of bits[2:0] of the status register
- * b[15] = 0 reserved
- * NOTE: The overrun bit could be used to set a flag indicating EC could
- * not keep up with the host.

- * Interrupt fires when number of bytes written
- * to eSPI/LPC I/O 80h-81h exceeds Por80_0 FIFO level
- * Issues:
- * 1. eSPI will not break 16-bit I/O into two 8-bit writes
- *    as LPC does. This means Port 80h hardware will capture
- *    only bits[7:0] of data.
- * 2. If Host performs write of 16-bit code as consecutive
- *    byte writes the Port 80h hardware will capture both but
- *    we do not know the order it was written.
- * 3. If Host sometimes writes one byte code to I/O 80h and
- *    sometimes two byte code to I/O 80h/81h how do we determine
- *    what to do?
- *
- * An alternative is to document Host must write 16-bit codes
- * to I/O 80h and 90h.  LSB to 0x80 and MSB to 0x90.
