This commit adds support for different iterations of ESPRESSObin.
The added variants are:
ESPRESSObin with soldered eMMC,
ESPRESSObin V7, compared to V5 some passive elements changed and ethernet
ports labels positions have been reversed,
ESPRESSObin V7 with soldered eMMC.
Please refer to:
584d7c5 ("mvebu: new subtarget cortex A53")
for instruction how to boot OpenWrt image placed on SD card. It is
advised for owners of V5 and previous with bootloader based on U-Boot
2015.01, to upgrade the latest version available at:
http://espressobin.net/tech-spec.

Convert whole target to Device Tree based board detection instead of
identifying devices by dts file name. With this we can drop mvebu.sh
translation script and rely on common method for model detection.

Add vendors in device names and also rename few device names, for easier
identyfying potential firmware to flash. The vendor and device string is
mainly derived from model/compatipble string in dts from particular
device, but since not all devices are well described, some of the renames
follow marketing names.

All of arm64 devices have part of variables repeatedly defined. Stack
them to common define, and reference it in each device recipe.

Since most of devices using SD card image to boot, use ext4 as boot
files system we can drop fat fs related packages. Also move packages
which are added repeatedly across subtargets to their default packages,
with droping the ones that are enabled in target kernel configugation.

Add initial support for Marvell Armada cortex-a53 based
DB-88F3720-DDR3-Modular development board.
Specifications:
- Dual core ARMv8 Cortex-A53 CPU (up to 1.0 GHz)
- 4Gb 16-bit DDR3/3L DRAM memory
- 128Mb SPI NOR flash memory
- 8Gb eMMC NAND flash memory
- 1 x SATA Rev 3.0 port
- 1 x PCI Express (PCIe) Gen 2.0 or 1 x mini PCI Express (PCIe) Gen 2.0
- 1 x 1G Ethernet port via RGMII (RJ45)
- 1 x SD card port
- 1 x USB3 (USB2 backward) host\device port via type C connector
- 1 x USB2 host port via type A connector
- 1 x serial COM port driven by the 88F3720 UART interface and converted to
USB via FTDI IC (option to connect the UART DB9 adapter)
- I2C Master Interface:
- 1 x EEPROM @ address 0x57
- 1 x I/O Expanders @ address 0x22
- Sample at Reset (SatR) memory device @ address 0x4C
- RTC clock generator PT7C4337AWE @ address 0x68
- USB3 switch PI5USB30213XEA @ address 0x0D
- ID component of PHY module @ address 0x24
- 1 x JTAG interface for CPU emulator
- 1 x SETM and JTAG debug interface
- 1 x power connector for HDD supply
- 1 x 12V DC jack power connector
- Board dimensions: 150 mm x 179 mm
- LED interface for system status
Booting from SD card:
1. reset U-Boot environment:
env default -a
saveenv
2. prepare U-Boot with boot script:
setenv bootcmd "load mmc 0:1 0x4d00000 boot.scr; source 0x4d00000"
saveenv
or manually:
setenv fdt_name armada-3720-db.dtb
setenv image_name Image
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/mmcblk1p2 rw rootwait; booti $kernel_addr - $fdt_addr'
saveenv

This commit introduces new subtarget for Marvell EBU Armada Cortex A53
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"
setenv bootcmd "ext4load mmc 0:1 ${fdt_addr} armada-3720-espressobin.dtb; ext4load mmc 0:1 ${kernel_addr} Image; booti ${kernel_addr} - ${fdt_addr}"
saveenv
3. Poweroff, insert SD card with OpenWrt image, boot and enjoy.
