Capricorn boards have WDT (WDT_SIEMENS_PMIC) and U-Boot is not configured
to trigger the WDT. Enable the "wdt" command to be able to stop the WDT
from the command line.

Currently if a gigabit-capable PHY is connected to FEC via RMII or MII, it
will advertise 1000FULL and 1000HALF to a link partner.
Different problems may arise here:
- usually with (R)MII between MAC and PHY the PHY's connection to magnetics
would have only 2 pairs route

The hack itself seems to be copied from Linux rti_wdt.c, but the WDT reset
principle is different in U-Boot. While Linux relies on correct frequencies
and timers and doesn't check the actual WDT counter value U-Boot driver
seems to be more robust: it does compare RTIDWDCN

If the RTI watchdog has been enabled in SPL, enabling it in U-Boot proper
fails because it can only be enabled once in HW and never stopped. This
however leads to a situation that wdt_cyclic() watchdog trigger is not
being started any longer and the WDT fires at some poin

eth_env_set_enetaddr_by_index() declaration is duplicated in eth_internal.h
and net.h, but all units including eth_internal.h already include net.h.
Remove the superfluous declaration.

Upstream Linux commit 3aa07f72894d.
If there's a disconnection while operating in eSS, there may be a delay
in VBUS drop response from the connector. In that case, the internal
link state may drop to operate in usb2 speed while the controller thinks
the VBUS is still high. The

When operating in USB 2.0 speeds (HS/FS), if GUSB2PHYCFG.ENBLSLPM or

As a micro-power optimization, let's only resume the

gonna work on SUPERSPEED or SUPERSPEED+, there's no
point in resuming the USB2 PHY.

Synopsys Databook 2.60a has a note that if we're

This patch implements that particular detail.
