configs: add defconfig for TS-4800

The TS-4800 is supported by mainline Linux as of 4.5 and by U-boot
as of v2016-07.

The package requires the custom ts4800-mbrboot routine.

A post-image script is provided to generate an image that can be
directly written to an SD card.

+Technologic Systems TS-4800
+===========================
+
+This document explains how to set up a basic Buildroot system for the
+Technologic Systems TS-4800 System on Module.
+
+The TS-4800 is a TS-SOCKET macrocontroller board based on the Freescale
+i.MX515 ARM Cortex-A8 CPU running at 800MHz. The TS-4800 features 10/100
+Ethernet, high speed USB host and device (OTG), microSD card, and 256MB
+XNAND drive.  More details on the board here:
+       http://wiki.embeddedarm.com/wiki/TS-4800
+
+The TS-4800 is supported by mainline Linux as of 4.5 and by U-boot as of
+v2016-07. The defconfig includes a custom 1st level bootloader located
+in boot/ts4800-mbrboot. This one scans the SD card's partition table to
+find partition having the 0xDA type, corresponding to U-boot.
+
+To build the default configuration you only have to:
+
+       $ make ts4800_defconfig
+       $ make
+
+The ouput looks like:
+       output/images/
+       ├── boot.vfat
+       ├── imx51-ts4800.dtb
+       ├── mbrboot.bin
+       ├── rootfs.ext2
+       ├── rootfs.ext4 -> rootfs.ext2
+       ├── rootfs.tar
+       ├── sdcard.img
+       ├── u-boot.bin
+       └── zImage
+
+The provided post-image script generates an image file containing 3
+partitions for U-boot, Linux kernel + device tree and rootfs
+respectively:
+       $ fdisk output/images/sdcard.img
+                          Device Boot Start    End Blocks Id  System
+       output/images/sdcard.img1          1    512    256 da  Non-FS data
+       output/images/sdcard.img2        513  16896   8192  c  W95 FAT32 (LBA)
+       output/images/sdcard.img3      16897 541184 262144 83  Linux
+
+This image can be directly written to an SD card.
+
+       $ sudo dd if=output/images/sdcard.img of=/dev/mmcblk0
+
+In order to test the image on TS-4800 board, a TS baseboard, such as
+TS-8xxx the serie, is needed to provide power, console header, RJ45
+connector etc.
