The bootloader does not always initialize the MDIO pins before booting
Linux. E.g. on version "U-Boot 2012.07 [Chaos Calmer 15.05.1,r35193] (Jul
25 2017 - 11:36:26)" this is the case when booting automatically without
activating the U-Boot console.
Without this change, the kernel boot will complain about missing PHYs:
libphy: ipq40xx_mdio: probed
ar40xx c000000.ess-switch: Probe failed - Missing PHYs!
libphy: Fixed MDIO Bus: probed
With this change it will work as expected:
libphy: ipq40xx_mdio: probed
ESS reset ok!
ESS reset ok!
libphy: Fixed MDIO Bus: probed

In 5.4 kernel old u32 array way of setting network features was dropped and linkmode is now the only way.
So lets migrate the EDMA driver to support linkmode.
Also, old get/set settings API for ethtool is also dropped so lets convert to new ksettings API while at it as it demands linkmode.
Now, gigabit works properly as well as ethtool.
Previously you would get this in ethtool:
root@OpenWrt:/# ethtool eth1
Settings for eth1:
Supports Wake-on: d
Wake-on: d
Current message level: 0x00000000 (0)
Link detected: yes
Now, features are properly advertised:
root@OpenWrt:/# ethtool eth1
Settings for eth1:
Supported ports: [ TP MII ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full

of_get_mac_address returns valid pointer or ERR_PTR since 5.2 via commit
d01f449c008a ("of_net: add NVMEM support to of_get_mac_address") so the
patch fixes following OOPs on nbg6617:
Unable to handle kernel paging request at virtual address ffffffed
CPU: 1 PID: 1 Comm: swapper/0 Not tainted 5.4.24 #0
PC is at edma_axi_probe+0x444/0x1114
LR is at bus_find_device+0x88/0x9c
Where the PC can be resolved to:
>>> l *edma_axi_probe+0x444
0xc067be5c is in edma_axi_probe (./include/linux/string.h:378).
>>> l *edma_axi_probe+0x43f
0xc067be57 is in edma_axi_probe (drivers/net/ethernet/qualcomm/essedma/edma_axi.c:936)
Which leads to the following code fragment:
935 mac_addr = of_get_mac_address(pnp);
936 if (mac_addr)
937 memcpy(edma_netdev[idx_mac]->dev_addr, mac_addr, ETH_ALEN);
Where using mac_addr=0xffffffed (-ENODEV) as source address in memcpy()
is causing the OOPs.

This patch adds support for the 8devices Habanero development board.
Specs are:
CPU: QCA IPQ4019
RAM: DDR3L 512MB
Storage: 32MB SPI-NOR and optional Parallel SLC NAND(Some boards ship with it and some without)
WLAN1: 2.4 GHz built into IPQ4019 (802.11n) 2x2
WLAN2: 5 GHz built into IPO4019 (802.11ac Wawe-2) 2x2
Ethernet: 5x Gbit LAN (QCA 8075)
USB: 1x USB 2.0 and 1x USB 3.0 (Both built into IPQ4019)
MicroSD slot (Uses SD controller built into IPQ4019)
SDIO3.0/EMMC slot (Uses the same SD controller)
Mini PCI-E Gen 2.0 slot (Built into IPQ4019)
5x LEDs (4 GPIO controllable)
2x Pushbutton (1 is connected to GPIO, other to SoC reset)
LCD ZIF socket (Uses the LCD controller built into IPQ4019 which has no driver support)
1x UART 115200 rate on J18
2x breakout development headers
12V DC Jack for power
DIP switch for bootstrap configuration
Installation instructions:
Since boards ship with vendors fork of OpenWrt sysupgrade can be used.

This fixes a typo in the device string for MAC address setup in
02_network and corrects the indent in the device's DTS files.
While at it, move the aliases section before the keys section to
have it closer to the top of the file.

1. Load Ramdisk via U-Boot
To set up the flash memory environment, do the following:
a. As a preliminary step, ensure that the board console port is connected to the PC using these RS232 parameters:
* 115200bps
* 8N1
b. Confirm that the PC is connected to the board using one of the Ethernet ports.
c. Set a static ip 192.168.99.8 for Ethernet that connects to board.
d. The PC must have a TFTP server launched and listening on the interface to which the board is connected.
e. At this stage power up the board and, after a few seconds, press 4 and then any key during the countdown.
U-BOOT> set serverip 192.168.99.9 && tftpboot 0x84000000 192.168.99.8:openwrt.itb && bootm
