+ARM/C5471-specific Configuration Options
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+	CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+	   be set to:
+
+	   CONFIG_ARCH=arm
+
+	CONFIG_ARCH_name - For use in C code:
+
+	   CONFIG_ARCH_ARM=y
+
+	CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+	   CONFIG_ARCH_CHIP=c5471
+
+	CONFIG_ARCH_CHIP_name - For use in C code
+
+	   CONFIG_ARCH_CHIP_C5471
+
+	CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+	   hence, the board that supports the particular chip or SoC.
+
+	   CONFIG_ARCH_BOARD=c5471evm (for the Spectrum Digital C5471 EVM)
+
+	CONFIG_ARCH_BOARD_name - For use in C code
+
+	   CONFIG_ARCH_BOARD_C5471EVM (for the Spectrum Digital C5471 EVM)
+
+	CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+	   of delay loops
+
+	CONFIG_ENDIAN_BIG - define if big endian (default is little
+	   endian)
+
+	CONFIG_ROM_VECTORS - should be defined for the C5471 because the
+	   interrupt vectors are in ROM
+
+	CONFIG_DRAM_END - the size of installed DRAM. Unique to c5471
+
+	CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+	   have LEDs
+
+	CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+	   stack. If defined, this symbol is the size of the interrupt
+	   stack in bytes.  If not defined, the user task stacks will be
+	  used during interrupt handling.
+
+	CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+  C5471 specific device driver settings
+
+	CONFIG_SERIAL_IRDA_CONSOLE - selects the IRDA UART for the
+	   console ant ttys0 (default is the modem UART).
+	CONFIG_UART_*_HWFLOWCONTROL - enables hardware flow control
+	CONFIG_UART_*_RXBUFSIZE - Characters are buffered as received.
+	   This specific the size of the receive buffer
+	CONFIG_UART_*_TXBUFSIZE - Characters are buffered before
+	   being sent.  This specific the size of the transmit buffer
+	CONFIG_UART_*_BAUD - The configure BAUD of the UART.  Must be
+	CONFIG_UART_*_BITS - The number of bits.  Must be either 7 or 8.
+	CONFIG_UART_*_PARTIY - 0=no parity, 1=odd parity, 2=even parity
+	CONFIG_UART_*_2STOP - Two stop bits
+
+  C5471 Ethernet Driver settings
+
+	CONFIG_C5471_NET_STATS
+	CONFIG_C5471_ETHERNET_PHY={ETHERNET_PHY_LU3X31T_T64,ETHERNET_PHY_AC101L}
+	CONFIG_NET_C5471_AUTONEGOTIATION
+	CONFIG_NET_C5471_BASET100
+	CONFIG_NET_C5471_BASET10
+
