Devices based on the AMD Alchemy

By default the YAMON bootloader only enables the UART's it is using, two at max. For Au1100/1550 only UART0 and UART3 are enabled, leaving UART1 non-functional. You can simply edit the reset source file named arch/init/reset_<name of your platform>.c to enable it. Check for the uart_enable register (Offset=0x0100 from the base address) in the databook. After you've enabled it, the Linux kernel serial driver is able to detect it.
