+Linux on the CRIS architecture
+==============================
 
-This is a port of Linux 2.4 to Axis Communications ETRAX 100LX embedded 
-network CPU. For more information about CRIS and ETRAX please see further
-below.
+This is a port of Linux to Axis Communications ETRAX 100LX,
+ETRAX FS and ARTPEC-3 embedded network CPUs.
+
+For more information about CRIS and ETRAX please see further below.
 
 In order to compile this you need a version of gcc with support for the
-ETRAX chip family. Please see this link for more information on how to 
+ETRAX chip family. Please see this link for more information on how to
 download the compiler and other tools useful when building and booting
 software for the ETRAX platform:

 What is CRIS ?
 --------------
 
 CRIS is an acronym for 'Code Reduced Instruction Set'. It is the CPU
 architecture in Axis Communication AB's range of embedded network CPU's,
-called ETRAX. The latest CPU is called ETRAX 100LX, where LX stands for
-'Linux' because the chip was designed to be a good host for the Linux
-operating system.
+called ETRAX.
 
 The ETRAX 100LX chip

-The previous version of the ETRAX, the ETRAX 100, sits in almost all of
-Axis shipping thin-servers like the Axis 2100 web camera or the ETRAX 100
-developer-board. It lacks an MMU so the Linux we run on that is a version
-of uClinux (Linux 2.0 without MM-support) ported to the CRIS architecture.
-The new Linux 2.4 port has full MM and needs a CPU with an MMU, so it will

+
+The ETRAX FS and ARTPEC-3 chips
+-------------------------------
 
-A version of the Axis developer-board with ETRAX 100LX (running Linux
-2.4) is now available. For more information please see developer.axis.com.
+The ETRAX FS is a 200MHz 32-bit RISC processor with on-chip 16kB
+I-cache and 16kB D-cache and with a wide range of device interfaces
+including multiple high speed serial ports and an integrated USB 1.1 PHY.
 
+The ARTPEC-3 is a variant of the ETRAX FS with additional IO-units
+used by the Axis Communications network cameras.
+
+See below link for more information:

+http://www.axis.com/products/dev_etrax_fs/index.htm

+ETRAX FS and ARTPEC-3 are both CRISv32 architectures.

- * PCF8563 RTC
- *
- * From Phillips' datasheet:
- *
- * The PCF8563 is a CMOS real-time clock/calendar optimized for low power
- * consumption. A programmable clock output, interrupt output and voltage
- * low detector are also provided. All address and data are transferred
- * serially via two-line bidirectional I2C-bus. Maximum bus speed is
- * 400 kbits/s. The built-in word address register is incremented
- * automatically after each written or read byte.
