  To: buildroot

The TS-7680 is an i.MX286 ARM ARM926EJ-S board with 10/100 Ethernet,
USB port, eMMC and CAN ports.

The TS-7680 uses a 3.14.28 Linux kernel provided by Technologic Systems:
https://github.com/embeddedarm/linux-3.14.28-imx28
This kernel is patched to compile with gcc version 5.x and later.

U-Boot is not provided as the manufacturer recommends not to update the
built-in bootloader.

For more informations please see:
https://wiki.embeddedarm.com/wiki/TS-7680

+Subject: [PATCH] ARM: 8158/1: LLVMLinux: use static inline in ARM ftrace.h
+
+With compilers which follow the C99 standard (like modern versions of gcc and
+clang), "extern inline" does the wrong thing (emits code for an externally
+linkable version of the inline function). In this case using static inline
+and removing the NULL version of return_address in return_address.c does
+the right thing.

+Subject: [PATCH] compiler-gcc: integrate the various compiler-gcc[345].h files
+
+commit f320793e52aee78f0fbb8bcaf10e6614d2e67bfc upstream.
+
+[ Upstream commit cb984d101b30eb7478d32df56a0023e4603cba7f ]
+
+As gcc major version numbers are going to advance rather rapidly in the
+future, there's no real value in separate files for each compiler
+version.
+
+Deduplicate some of the macros #defined in each file too.
+
+Neaten comments using normal kernel commenting style.

+Technologic Systems TS-7680 SBC
+===============================
+
+This document explains how to set up a basic Buildroot system for
+the Technologic Systems TS-7680 Single Board Computer.
+
+The TS-7680 SBC is based on the Freescale i.MX286 ARM ARM926EJ-S
+running at 454MHz. The TS-7680 features are 10/100 Ethernet ports,
+Wi-Fi, microSD card, eMMC, NOR Flash, USB host port, CAN ports,
+relays and ADC/DAC. More details on the board here:
+https://wiki.embeddedarm.com/wiki/TS-7680
+
+The TS-7680 uses a 3.14.28 Linux kernel provided by
+Technologic Systems.
+
+To build the default configuration you only have to run:
+
+  $ make ts7680_defconfig
+  $ make
+
+The output looks like:
+output/images
+??? imx28-ts7680.dtb
+??? rootfs.ext2
+??? rootfs.ext4 -> rootfs.ext2
+??? rootfs.tar
+??? sdcard.img
+??? uImage
+
+The provided post-image script generates an image file containing
+two partitions. The first one is unused, but mandatory as the
+TS-7680 built-in bootloader loads the Linux uImage from the /boot
+directory in the second partition. The second partition contains the
+rootfs with the Linux uImage into the /boot directory.
+
+  $ fdisk output/images/sdcard.img
+  output/images/sdcard.img1          1      1       1  512B  0 Empty
+  output/images/sdcard.img2          2 524289  524288  256M 83 Linux
+
+This image can be directly written to an SD card.
+
+    $ sudo dd if=output/images/sdcard.img of=/dev/mmcblk0
+
+To boot with Buildroot, insert this SD card on the board, make sure
+the SD jumper is present and the U-Boot jumper is not.
+
+The bootloader comes pre-flashed on the board on an SPI flash. Since
+updating the bootloader is risky and not trivial, it is not included
+in the Buildroot defconfig. Refer to
+https://wiki.embeddedarm.com/wiki/TS-7680#U-Boot for details on
+which U-Boot config to use and how to flash it.
