New board: SolidRun ClearFog Base
My goal was to rely on upstreamed features as much as possible, which means that some bits are only half-baked for now: - Due to the DTS restructuring in upstream kernel, we require 4.11+. The latest LTS or CIP kernels do not know about the -Base model. - Linux has no generic support for SFP cages (yet). It seems that this has hit the net-next tree in August 2017, but there's been no release (it's probably targettting 4.14). Also, the merge only included the required infrastructure; the mvneta driver conversion is not included. Patches which finalize this exist in Russel King's tree and also in random vendor trees. - There's no access to the SPI flash in these versions of uboot/linux/dts. Signed-off-by: Jan Kundrát <jan.kundrat@cesnet.cz> [Arnout: - rename to solidrun_clearfog_defconfig; - specify kernel headers version (default is now 4.15); - remove ext2 fs size override, the 4 extra MB are not needed; - U-Boot needs dtc and openssl; - add comments to defconfig; - update .gitlab-ci.yml; - mention in readme.txt that SFP support is missing; - add Jan to DEVELOPERS. ] Signed-off-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be>

+SolidRun Clearfog Base
+This file documents Buildroot's support for the Clearfog Base by Solid Run.
+Vendor's documentation:
+Warning for eMMC variant of the MicroSoM
+If you bought a MicroSoM version that includes an on-board eMMC flash, the
+built-in microSD card slot *WILL NOT WORK*. The Internet says that you have to
+upload the first bootloader via UART. This manual does not cover these steps;
+only MicroSoMs without the eMMC are supported.
+There's no access to the SPI flash in this combination of kernel/uboot/dts.
+There is no support for the SFP.
+Start with the default Buildroot's configuration for Clearfog:
+ make solidrun_clearfog_defconfig
+Build all components:
+ make
+The results of the build are available in ./output/images.
+Create a bootable SD card
+To determine the device associated to the SD card have a look in the
+/proc/partitions file:
+ cat /proc/partitions
+Buildroot prepares a bootable "sdcard.img" image in the output/images/
+directory, ready to be dumped on a microSD card. Launch the following
+command as root:
+ dd if=./output/images/sdcard.img of=/dev/<your-microsd-device>
+*** WARNING! The script will destroy all the card content. Use with care! ***
+For details about the medium image layout, see the definition in
+Boot the Clearfog board
+Here's how to boot the board:
+- Set up the DIP switches for microSD boot. The correct values are:
+ 1: off, 2: off, 3: ON, 4: ON, 5: ON. In this scheme, switch #1" is closer to
+ the ethernet ports and #5 is closer to the microSD card, "ON" means towards
+ the SOM, and "off" means towards the SFP cage.
+- Connect to the board's console over the microUSB port.
+- Insert the SD card into the slot on the board (pins up).
+- Power up the board.
