42c66f057f drivers: net: fsl_enetc: add write_hwaddr() for LS1028A
The LS1028A SoC is special in the handling of the MAC addresses. We need
to write to the IERB version of the PSIPMAR0/1 register. This value will
be sampled into the corresponding port PSIPMAR0/1 register if the PCI
memory access is enabled.

bcee8d6764 dm: gpio: Allow control of GPIO uclass in SPL
At present if CONFIG_SPL_GPIO_SUPPORT is enabled then the GPIO uclass
is included in SPL/TPL without any control for boards. Some boards may
want to disable this to reduce code size where GPIOs are not needed in
SPL or TPL.

Add a new Kconfig option to permit this. Default it to 'y' so that
existing boards work correctly.

Change existing uses of CONFIG_DM_GPIO to CONFIG_IS_ENABLED(DM_GPIO) to
preserve the current behaviour. Also update the 74x164 GPIO driver since
it cannot build with SPL.

This allows us to remove the hacks in config_uncmd_spl.h and
Makefile.uncmd_spl (eventually those files should be removed).

I've noticed that in most cases when genphy_update_link() is called, the
ethernet driver (mt7628-eth in this case) fails with the first ethernet

the delay in the link check look from 1 to 50 ms and moving it below the
BMSR register read fixes this issue, resulting in a stable ethernet
traffic, even after initial link autonogotiation.

945dd965dd net: rtl8169: Support RTL-8168c/8111c
This version of the RTL-8168 chip can be found on some add-in cards sold
by CSL-Computer GmbH & Co. KG. The chip isn't special in any way, but it
needs to have the ChipCmd register programmed after the DMA descriptors
have been set up, so make sure that happens by adding an entry to the
chip information table.

Changes to mvpp2.c require the MVMDIO module which in turn uses
DM_MDIO.

2a42870778 net: mvpp2: use new MVMDIO driver
This commit ports mvpp2 to use the recently introduced Marvell MDIO
(MVMDIO) driver.  It removes direct interaction with the SMI & XSMI
busses.  This commit is based in part on earlier work by
Ken Ma <make@marvell.com> in Marvell's own downstream repo:
https://github.com/MarvellEmbeddedProcessors/u-boot-marvell/commit/c81dc39.

The above refrenced work was based on an MVMDIO implementation that
never made it into U-Boot.  With this patch the mvpp2 driver switches
to use the new MVMDIO driver that is based on a more universal
mdio-uclass implementation.

623948377a net: mvpp2: mark phy as invalid in case of missing appropriate driver
If the phy doesn't match with any existing u-boot drivers, the phy
framework will connect it to the generic one which uid ==
0xffffffff. In this case, act as if the phy wouldn't be declared in
dts. Otherwise, in case of 3310 (for which the driver doesn't exist)
the link is marked as always down. Removing phy entry from dts in case
of 3310 is not a good option because it is required for the
phy_fw_down procedure.

This patch fixes the issue with the link always down on MCBIN board.

nhed: added NULL deref test.

13b725fd24 net: mvpp2x: fix traffic stuck after PHY start error
Issue:
- Network stuck if autonegotion fails.

Issue root cause:

- When autonegotiation fails during port open procedure, the packet
  processor configuration does not finish and open procedure exits
  with error.
- However, this doesn't prevent u-boot network framework from
  calling send and receive procedures.
- Using transmit and receive functions of misconfigured packet
  processor will cause traffic to get stuck.

Fix:

- Continue packet processor configuration even if autonegotiation
  fails.  Only error message is triggered in this case.
- Exit transmit and receive functions if there is no PHY link
  indication.
- U-boot network framework now calls open procedure again during next
  transmit initiation.

253a5ff871 net: phy: dp83867: io impedance is not dependent on RGMII delay
Based on commit 27708eb5481b ("net: phy: dp83867: IO impedance is not
dependent on RGMII delay") of mainline linux kernel.

The driver would only set the IO impedance value when RGMII internal delays
were enabled.  There is no reason for this.  Move the IO impedance block
out of the RGMII delay block.
