This patch adds sysupgrade, uboot-env and networking support
for Methode uDPU device.
Device features 4 partitions:
-----------------------------------------
| boot | recovery | rootfs | misc |
| (ext4) | (ext4) | (fsf2) | (f2fs) |
_________________________________________
Idea was to use f2fs only but the u-boot currently lacks support
so first 2 partition are ext4 to be u-boot readable, and this was
a reason why custom build and sysupgrade sections were required.
On the sysupgrade, boot and rootfs partitions are updated, firmare
image and user configuration is saved on the misc partition and if
the upgrade was successfull, recovery partition will be updated on
after the reboot from preinit script. If the sysupgrade fails for any
reason, device will fallback to recovery initramfs image.

This adds initial support for micro-DPU (uDPU) board which is based on
Armada-3720 SoC. micro-DPU is the single-port FTTdp distribution point
unit made by Methode Electronics which offers complete modularity with
replaceable SFP modules both for uplink and downlink (G.hn over
twisted-pair, G.hn over coax, 1G and 2.5G Ethernet over Cat-5e cable).
On-board features:
- 512 MiB DDR3
- 2 x 2.5G SFP via HSGMII SERDES interface to the A3720 SoC
- USB 2.0 Type-C connector
- 4GB eMMC
- ETSI TS 101548 reverse powering via twisted pair (RJ45) or coax (F Type)
uDPU is intented to run on kernel 4.19 on newer due to the SFP and hardware support.

Not all versions of ESPRESSObin require SD card, but can
be booted from the internal emmc flash (mmc dev 1) instead.
Add a simple check in the bootscript to see which mmc device
is detected and boot from it using mmcdev variable.

This commit adds support for different iterations of ESPRESSObin.
The added variants are:

ESPRESSObin V7, compared to V5 some passive elements changed and ethernet
ports labels positions have been reversed,
ESPRESSObin V7 with soldered eMMC.

All of U-Boot scripts repeat the same pattern with only Device Tree blob
name changing for respective device. Therefore create generic scripts
which will be altered on demad by image build process, and create
BOOT_SCRIPT variable which can be added to device recipe and will allow
referencing the same script by many device recipes. This will allow to
slim down the ammount of files in buildroot tree and avoid needlessly
incrementing amount of boot scripts if new devices will be added.

processor based devices.
The first device is Globalscale ESPRESSObin. Some hardware specs:
SoC: Marvell Armada 3700LP (88F3720) dual core ARM Cortex A53
processor up to 1.2GHz
RAM: 512MB, 1GB or 2GB DDR3
Storage: SATA interface
µSD card slot with footprint for an optional 4GB EMMC
4MB SPI NOR flash for bootloader
Ethernet: Topaz Networking Switch (88E6341) with 3x GbE ports
Connectors: USB 3.0
USB 2.0
µUSB port connected to PL2303SA (USB to serial bridge
controller) for UART access
Expansion: 2x 46-pin GPIO headers for accessories and shields with
I2C, GPIOs, PWM, UART, SPI, MMC, etc
MiniPCIe slot
Misc: Reset button, JTAG interface
Currently booting only from µSD card is supported.
The boards depending on date of dispatch can come with various U-Boot
versions. For the newest version 2017.03-armada-17.10 no manual
intervention should be needed to boot OpenWrt image. For the older ones
it's necessary to modify default U-Boot environment:
1. Interrupt boot process to run U-Boot command line,
2. Run following commands:
(for version 2017.03-armada-17.06 and 2017.03-armada-17.08)
setenv bootcmd "load mmc 0:1 0x4d00000 boot.scr; source 0x4d00000"
saveenv
(for version 2015.01-armada-17.02 and 2015.01-armada-17.04)
setenv bootargs "console=ttyMV0,115200 root=/dev/mmcblk0p2 rw rootwait"

Adds support for the Turris Omnia and builds an eMMC sysupgrade image in
the same format as the SolidRun ClearFog.
An initramfs image in the simple yet Omnia-specific 'medkit' image format
is also built in order to ease the initial flashing process.
Notable hardware support omissions are support for switching between SFP
cage and copper PHY, and RGB LED control.
Due to a current limitation of DSA, only 1/2 CPU switch uplinks are used.
Specifications:
- Marvell Armada 385 1.6GHz dual-core ARMv7 CPU
- 1GB DDR3 RAM
- 8GB eMMC Flash
- 5x Gigabit LAN via Marvell 88E6176 Switch (2x RGMII CPU ports)
- 1x switchable RJ45 (88E1514 PHY) / SFP SGMII WAN
- 2x USB 3.0
- 12x dimmable RGB LEDs controlled by independent MCU
- 3x Mini PCIe slots
- Optional Compex WLE200N2 Mini PCIe AR9287 2x2 802.11b/g/n (2.4GHz)
- Optional Compex WLE900VX Mini PCIe QCA9880 3x3 802.11ac (2.4 / 5GHz)
- Optional Quectel EC20 Mini PCIe LTE modem
Flash instructions:
If the U-Boot environment has been modified previously (likely manually via
serial console), first use serial to reset the default environment.
=> env default -a
=> saveenv
Method 1 - USB 'medkit' image w/o serial
- Copy openwrt-mvebu-turris-omnia-sysupgrade.img.gz and
omnia-medkit-openwrt-mvebu-turris-omnia-initramfs.tar.gz to the root of a
USB flash drive formatted with FAT32 / ext2/3/4 / btrfs / XFS.
Note that the medkit MUST be named omnia-medkit*.tar.gz
- Disconnect other USB devices from the Omnia and connect the flash drive
to either USB port.
- Power on the Omnia and hold down the rear reset button until 4 LEDs are
illuminated, then release.
- Wait approximately 2 minutes for the Turris Omnia to flash itself with
the temporary image, during which LEDs will change multiple times.
- Connect a computer to a LAN port of the Turris Omnia with a DHCP client
- (if necessary) ssh-keygen -R 192.168.1.1
- ssh root@192.168.1.1
$ mount /dev/sda1 /mnt
$ sysupgrade /mnt/openwrt-mvebu-turris-omnia-sysupgrade.img.gz
- Wait another minute for the final OpenWrt image to be flashed. The Turris
Omnia will reboot itself and you can remove the flash drive.
Method 2 - TFTP w/ serial
- Extract omnia-medkit-openwrt-mvebu-turris-omnia-initramfs.tar.gz and copy
dtb + zImage to your TFTP server (rename if desired)
- Connect Turris Omnia WAN port to DHCP-enabled network with TFTP server
- Connect serial console and interrupt U-Boot
=> dhcp
=> setenv serverip <tftp_server_ip_here>
=> tftpboot 0x01000000 zImage
=> tftpboot 0x02000000 dtb
=> bootz 0x01000000 - 0x02000000
- OpenWrt will now boot from ramdisk
- Download openwrt-mvebu-turris-omnia-sysupgrade.img.gz to /tmp/
$ sysupgrade /tmp/openwrt-mvebu-turris-omnia-sysupgrade.img.gz
- Wait another minute for the final OpenWrt image to be flashed. The Turris
