[Buildroot] [PATCH 1/1] configs/globalscale_espressobin: new defconfig

Basic support for the Marvell ESPRESSObin, by Globalscale Technologies.
http://espressobin.net
The kernel config has been extended with a fragment to enable switchcore
support, DSA drivers, and VLAN filtering in the bridge. To make use of
this you need a custom libnl based application, or the iproute2 suite
rather than the brctl tools, which don't support the VLAN filtering.

+Marvell ESPRESSObin
+===================
+
+This default configuration allows you to quickly get up and running with
+the Marvell ESPRESSObin board by Globalscale Technologies Inc.
+
+The ESPRESSObin is based on the Marvell Armada 88F3720 SoC, coupled with
+a Marvell 88E6341 switch core "Topaz", with three exposed gigabit ports.

+ Fig 1: Overview of board
+
+Notice difference in Ethernet port layout compared to the Globalscale
+docs. They order the ports; LAN2, LAN1, WAN (left to right in figure
+above). For more information, see http://espressobin.net
+
+
+Building
+--------
+
+ $ make globalscale_espressobin_defconfig
+ $ make
+
+This generates the kernel image, the devicetree binary, the rootfs as a
+tar.gz, and a filesystem image containing everything.
+
+All build artifacts are located in `output/images/`
+
+
+Booting
+-------
+
+To boot, you need a UART connection, using the on-board micro USB port
+set to 115200 8N1.
+
+By default, the ESPRESSObin comes with a pre-flashed U-Boot set up to
+load the kernel, device-tree and rootfs from SPI NOR flash. The board
+jumpers can be changed to boot from different sources, see the quick
+start guide for each board revision for details:
+
+- ftp://downloads.globalscaletechnologies.com/Downloads/Espressobin/ESPRESSObin%20V5/
+- ftp://downloads.globalscaletechnologies.com/Downloads/Espressobin/ESPRESSObin%20V7/
+
+Note: the v5, and earlier, cannot boot from sdcard, so you have to set
+up the factory U-Boot to boot into Buildroot:
+
+1. Flash rootfs image to sdcard drive, your `of=` device may differ:
+
+ $ sudo dd if=output/images/sdcard.img of=/dev/mmcblk0 bs=1M
+ $ sync
+
+2. Boot board from SPI NOR, interrupt boot by pressing any key ...
+3. Check with `printenv` that the default setup is OK, otherwise ensure
+ the following are set, and define `bootcmd` for automatic boot:
+
+ > setenv kernel_addr 0x5000000
+ > setenv fdt_addr 0x1800000
+ > setenv fdt_name boot/armada-3720-espressobin.dtb
+ > setenv console console=ttyMV0,115200 earlycon=ar3700_uart,0xd0012000
+ > setenv bootcmd 'mmc dev 0; ext4load mmc 0:1 $kernel_addr $image_name;ext4load mmc 0:1 $fdt_addr $fdt_name;setenv bootargs $console root=/dev/mmcblk0p1 rw rootwait; booti $kernel_addr - $fdt_addr'
+
+4. Call the boot command, or `reset` the board to start:
+
+ > run bootcmd
+
+
+Networking
+----------
+
+To enable Ethernet networking, load the `mv88e6xxx` kernel module, and
+bring up each respective interface needed:
+
+ # modprobe mv88e6xxx
+ # ifconfig wan up
+
+A more advanced scenario is setting up switching between the ports using
+the Linux bridge. The kernel switchdev layer, and DSA driver, ensure
+switch functions are "offloaded" to the HW switch, i.e., all traffic
+between LAN ports never reach the CPU. For this you need the iproute2
+suite of tools.
