- * The 440SPe provices 32 bits of GPIO. By default all GPIO pins
- * are disabled, and must be explicitly enabled by setting a
- * bit in the SDR0_PFC0 indirect DCR. Each GPIO maps 1-to-1 with the
- * corresponding bit in the SDR0_PFC0 register (note that bit numbers
- * reflect the PowerPC convention where bit 0 is the most-significant
- * bit).
- *
- * Katmai specific:
- * RS232_RX_EN# is held HIGH during reset by hardware, keeping the
- * RS232_CTS, DSR & DCD signals coming from the MAX3411 (U26) in
- * Hi-Z condition. This prevents contention between the MAX3411 (U26)
- * and 74CBTLV3125PG (U2) during reset.
- *
- * RS232_RX_EN# is connected as GPIO pin 30. Once the processor
- * is released from reset, this pin must be configured as an output and
- * then driven high to enable the receive signals from the UART transciever.
