The Alchemy SOC family is based on the Alchemy-proprietary MIPS32-compatible 'Au1' core. Models produced are the Au1000, Au1100, Au1500, Au1550, Au1200 series and Au1300 series, with the Au1000, Au1500, Au1550 targeted at network appliances and Au1100, Au1200 and Au1300 intented for multimedia devices.
Linux is supported on all Alchemy evaluation boards (DB1xxx series), and some third party boards, with some peripherals (USB OTG/device controller, video decoder, camera interface, ...) still missing drivers.
Alchemy Semiconductor was acquired by AMD in 2002, which in Summer 2006 sold the Alchemy processor line to Raza Microelectronics, Inc. In December 2007, Raza Microelectronics changed its name to RMI, Inc.. In June 2009, NetLogic Microsystems acquired RMI for $183.4 million in stock, which in turn was acquired by Broadcom in September 2011.

By default the YAMON bootloader only enables the UARTs 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.
