The CN9130 SoC (an ARMADA 8K type) has both a NAND Flash Controller and
a generic local bus controller (Device Bus Controller) that share common
pins.
With a board design that incorporates both a NAND flash and uses
the Device Bus (in our case for an SRAM) accessing the Device Bus device
fails unless the NfArbiterEn bit is set. Setting the bit enables
arbitration between the Device Bus and the NAND flash.
Since there is no obvious downside in enabling this for designs that
don't require arbitration, we always enable it.

While testing the ethernet interface on a Variscite symphony carrier
board using an imx8mn SOM with an onboard ADIN1300 PHY (EC hardware
configuration), the ethernet PHY is not detected.
The ADIN1300 datasheet indicate that the "Management interface
active (t4)" state is reached at most 5ms after the reset signal is
deasserted.
The device tree in Variscite custom git repository uses the following
property:
phy-reset-post-delay = <20>;
Add a new MDIO property 'reset-deassert-us' of 20ms to have the same
delay inside the ethphy node. Adding this property fixes the problem
with the PHY detection.
Note that this SOM can also have an Atheros AR8033 PHY. In this case,
a 1ms deassert delay is sufficient. Add a comment to that effect.

Before this change the FR_TXFF (Transmit FIFO full) bit (5 in
HW_UARTDBG_FR) has been used to assess if there is still data pending
to be sent via UART.
This approach is problematic, as it may happen that serial is in the
middle of transmission (so the TX FIFO is NOT full anymore) and this
test returns true infinitely. As a result, for example in _serial_flush()
DM serial function we are locked in endless while().
The fix here is to test explicitly if the TX FIFO is empty.
