When checking the outcome of the PHY autonegotiation status, at803x
currently returns false in case the SGMII side is not established.
Due to a hardware-bug, ag71xx needs to fixup the SoCs SGMII side, which
it can't as it is not aware of the link-establishment.
This commit allows to ignore the SGMII side autonegotiation status to
allow ag71xx to do the fixup work.

The QCA955X is affected by a hardware bug which causes link-loss of the
SGMII link between SoC and PHY. This happens on change of link-state or
speed.
It is not really known what causes this bug. It definitely occurs when
using a AR8033 Gigabit Ethernet PHY.
Qualcomm solves this Bug in a similar fashion. We need to apply the fix
on a per-device base via platform-data as performing the fixup work will
break connectivity in case the SGMII interface is connected to a Switch.
This bug was first proposed to be fixed by Sven Eckelmann in 2016.

This commit adds support for the AVM Fritz!WLAN Repeater 450E
SOC: Qualcomm QCA9556 (Scorpion) 560MHz MIPS74Kc
RAM: 64MB Zentel A3R12E40CBF DDR2
FLASH: 16MiB Winbond W25Q128 SPI NOR
WLAN1: QCA9556 2.4 GHz 802.11b/g/n 3x3
INPUT: WPS button
LED: Power, WiFi, LAN, RSSI indicator
Serial: Header Next to Black metal shield
Pinout is 3.3V - RX - TX - GND (Square Pad is 3.3V)
The Serial setting is 115200-8-N-1.
Tested and working:
- Ethernet
- 2.4GHz WiFi (correct MAC)
- Installation via EVA bootloader
- OpenWRT sysupgrade
- Buttons
- Most LEDs
Not working:
- 2 RSSI LEDs
AVM used for RSSI{0,1} two of the Ethernet PHYs LEDs which they
control over MDIO. Our driver doesn't expose these LEDs as GPIOs.
While it is possible to implement this feature, it would require an
additional kernel patch for a minor functionality.
Installation via EVA:
In the first seconds after Power is connected, the bootloader will
listen for FTP connections on 192.168.178.1. Firmware can be uploaded
like following:
ftp> quote USER adam2
ftp> quote PASS adam2
ftp> binary
ftp> debug
ftp> passive
ftp> quote MEDIA FLSH
ftp> put openwrt-sysupgrade.bin mtd1
Note that this procedure might take up to two minutes.
You need to powercycle the Device afterwards to boot OpenWRT.
