  To: barebox

This patch adds basic support for the TX27 CPU module.
It has been tested so far using OpenOCD to write it into memory and execute.
Environment loading and saving from NAND seems to work correctly, further
testing will be focused on booting from NAND.

Since I don't have any datasheets of the IIM in the i.MX27 I would appreciate
some help with getting the serial number and the ethernet MAC from there. Can
anyone shine some light here?

+@page tx27 KARO's TX27 CPU module
+
+@section tx27_cpu_card The TX27 CPU module
+
+The TX27 module is manufactured by Ka-Ro (http://www.karo-electronics.de/) in Germany.
+
+This module is based on an i.MX27 CPU. The SystemOnModule is equiped with:
+
+- Freescale i.MX27 SoC @ 400MHz
+- 64 MiB mobile DDR_SDRAM (128 MiB on request)
+- 128 MiB NAND K9F1G08R0B (1.8 V)
+- DS1339 RTC
+- LAN8700 Phy
+- Form factor: 26mm SO-DIMM
+
+For more information about the TX27 module, please check http://www.karo-electronics.de/tx27.html.
+
+
+@section tx27_baseboards Supported baseboards
+
+The only supported baseboard is the KARO's Starterkit 5:
+- DIMM200 TX socket
+- Two SD-card sockets
+- USB 2.0 OTG and USB 2.0 Host connector
+- D-SUB 15 VGA connector
+- 40pin LCD flat cable header
+- 3.5mm headphone connector
+- JTAG interface
+- UCB1400 audio codec & touchscreen controller
+- RS232 on 10pin flat cable and SUB-D header
+- All pins of the TX socket are connected to daughter board slot for easy application design-in
+- 10/100 Mbit/s Ethernet
+- 5VDC Power Supply by USB-OTG or screw header.
+- size 100mm x 160mm
+
+
+@section tx27_stk5_howto How to get barebox for 'KARO's Starterkit 5'
+
+Using the default configuration:
+
+@verbatim
+make ARCH=arm tx27stk5_defconfig
+@endverbatim
+
+Build the binary image:
+
+@verbatim
+make ARCH=arm CROSS_COMPILE=armv5compiler
+@endverbatim
+
+@note replace the armv5compiler with your ARM v5 cross compiler.
+
+@section tx27_mlayout Memory layout when barebox is running:

+@li 0xa0000100 start of kernel's boot parameters
+@li below malloc area: stack area
+@li below barebox: malloc area
