To: buildroot
This patch adds support for Acmesystems' AriaG25 SOM and the
corresponding Terra demo board.
The AriaG25 config is fairly basic, it provides only the minimal
configuration to get the module booting.
The Terra config instead provides many userspace tools.

+# AriaG25 / Terra board support
+
+Aria G25 is a cost-effective System-on-Module (SoM) thought of to drastically reduce the development time needed to design a low-power and low-EMI Linux Embedded device.
+
+Terra board is a complete hardware solution conceived to:
+
+* Evaluate the Aria G25 Linux embedded module for your own hardware design (schematic, bom, etc are available here)
+
+* Create concept prototypes using the Daisy add-on boards system for in-field applications
+
+* Build end-user products
+
+
+## AriaG25 Getting started
+
+To build a new minimal AriaG25 rootfs simply load corresponding ariag25_defconfig file. The config is fairly basic with only the kernel and busybox selected.
+
+To make the board bootable please follow the instruction on the producer website:
+
+[http://acmesystems.it/binary_repository](http://acmesystems.it/binary_repository)
+
+You will only need the correct boot.bin file for your board type, everithing else like kernel, dtb and roots are built by buildroot inside images directory.
+
+## Terra getting started
+
+To build a new minimal AriaG25 rootfs simply open the corresponding ariag25_demo_terra_defconfig file. This configuration is a bit more complete than the other and provides python, networking support and ssh access. It's meant to be usable as a reference for running example code you can find on the producer website:
+
+[http://acmesystems.it/tutorials](http://acmesystems.it/tutorials)
+
+Networking is configured for DHCP on the eth0.
+
+Please note that this configuration needs the correct boot.bin file, please refer to the AriaG25 getting started to know how to obtain it.

Dear Angelo Compagnucci,
Thanks for this patch. See my comments below.
The title of the patch should rather be something like:
board: add support for Acmesystems Ariag25 and Terra boards

Lines should be wrapped at a reasonable length, and the markdown wiki
syntax should not be used. The file should be named readme.txt. See all

This file should be named linux-<version>.config so that we know it's
the kernel configuration.
What are the differences compared to the at91_dt_defconfig available in
the kernel tree? We generally prefer to use the built-in defconfig
files from the kernel, when they are appropriate.

This Device Tree file is already part of the mainline kernel, why do we
need to add it in Buildroot ?

Add:
BR2_arm926t=y
to make sure we use the correct CPU architecture.

Not needed.

Please lock down the kernel headers versions, like is done in all other
defconfig files:
# Lock to 3.12 headers to avoid breaking with newer kernels
BR2_KERNEL_HEADERS_VERSION=y
BR2_DEFAULT_KERNEL_VERSION="3.12.2"

This will have to be modified to use the Device Tree file built into
the mainline kernel.

I honestly don't think it's really worth having a demo whose purpose is
just to enable Python and Dropbear. Could you submit a patch without
this demo configuration, it will have a higher chance of being merged.
Thanks!

Hi Angelo,
Do you plan to still take into account Thomas's comments and repost?
For the time being, we've marked this patch as Changes Requested in patchwork
