+Subject: [PATCH] x86: (ts5500) add board support for TS-5400
+
+This patch extends the TS-5500 board support to identify the compatible
+TS-5400 Single Board Computer (ID 0x40).
+
+It also adds a new "name" sysfs attribute for more human readable
+identification, actually printing "TS-5500" or "TS-5400".

+Technologic Systems TS-5x00 SBCs
+================================
+
+This document explains how to set up a basic Buildroot system for the
+Technologic Systems TS-5x00 serie of x86-based Single Board Computers.
+
+TS-5x00 Single Board Computers are based on the AMD Elan520 processor. For more
+information please have a look at http://wiki.embeddedarm.com/wiki/#AMD
+
+The kernel configuration works for any AMD Elan520-based SBCs, but the support
+is enhanced for the TS-5500 and TS-5400 models (on-board devices registration
+and additional sysfs attributes under /sys/devices/platform/).
+
+To build the default configuration you only have to:
+
+    $ make ts5x00_defconfig
+    $ make
+
+You will need a Compact Flash card of sufficient size and the first or only
+partition configured as Linux type, with the bootable flag.
+
+You can transfer the system on the partition then optionally resize it with:
+
+    # dd if=output/images/rootfs.ext4 of=/dev/sdX1
+    # resize2fs /dev/sdX1
+
+Or you can just extract the root filesystem to the partition with:
+
+    # mount /dev/sdX1 /mnt
+    # tar -pxf output/images/rootfs.tar -C /mnt
+    # umount /mnt
+
+To install the bootloader, you will need to copy the MBR:
+
+    # cat output/images/syslinux/mbr.bin > /dev/sdX
+
+Then install SYSLINUX in the mounted partition:
+
+    # mount /dev/sdX1 /mnt
+    # output/host/sbin/extlinux --install /mnt/boot/syslinux
+    # umount /mnt
+
+IMPORTANT: In order for the board to boot the Compact Flash with a recent
+config, the BIOS must use Logical Block Addressing (LBA). You can do it by
+choosing "Ide 0: AUTOCONFIG, LBA" under "IDE DRIVE GEOMETRY" in the "Basic CMOS
+Configuration" screen. For details about the CMOS setup, please see:
+http://wiki.embeddedarm.com/wiki/TS-5500#System_BIOS_Setup_Screens
+
+Connect a terminal program to the rs232 connector marked "COM2"
+with baudrate set to 115200, insert the Compact Flash card into the socket,
+power up the board, and enjoy.
