When an error is detected in the TSEC receive path, the driver currently
prints an error message, but leaves the corresponding packet descriptor
in its old state (i.e. owned by the CPU side). As a result, the packet
queue can be starved of available buffers if enough errors happen.
To recover from errors, re-arm the packet buffer descriptor after an
error has been detected.
Errors can be provoked by changing a PHY with phy-mode = "rgmii-id" to
phy-mode = "rgmii".

The TI DP83822 does have support for configurable RGMII RX/TX clock
shift, add support for parsing DT properties which describe the RX/TX
clock shift configuration and configuration of the matching bits in
RCSR register.
The shift is only configurable on DP83822, the other PHYs supported
by this PHY driver, namely DP83825/DP83826 variants, do not implement
this functionality and the RCSR bits used to configure the clock shift
are missing from those PHYs.
The shift is configurable separately for RX and TX path. Each path can
either enable the shift or disable the shift using single bit. In case
the shift is disabled, a delay of 0ns is added to the path, otherwise
a delay of 3.5ns is added to the path.
Note that the two RCSR bits 11 and 12 have inverted logic, RCSR bit 12
enables RX internal shift when SET, while RCSR bit 11 enables TX shift
when UNSET.

1. Bug fixed for doorbell in secure device manager mailbox driver
2. Enhancement on SoCFPGA dwc_eth_xgmac driver
3. Enhancement on DW MAC driver
4. Improved the error message and status for SoC64 device FPGA
configuration driver
5. Updated existing watchdog in system manager to support new SM device
This patch adds support for configuring the ethernet MAC mode independently
from the PHY mode on our SoC FPGA board. Specifically, this is necessary
for a scenario where the ethernet controller MAC is connected to the
FPGA HVIO with a different GMII interface, and the FPGA output is routed
to the PHY using a RGMII interface.
To support this configuration, a mechanism is introduced to handle
separate MAC mode settings, ensuring that the MAC controller and PHY
can operate correctly with their respective interface modes.
If mac-mode is not defined, the MAC mode will default to the PHY mode,
ensuring compatibility and proper operation between the MAC and PHY.

An issue was identified where selecting the phy-mode as
rgmii-id in the device tree source (DTS) would cause the
`dwc_eth_xgmac_socfpga` driver to raise an unsupported phy mode error.
From the MAC controller's perspective, the rgmii and rgmii-id
phy modes are effectively identical. To address this, both
modes will now be configured to rgmii in the MAC controller.
This change ensures that the rgmii-id phy mode is properly
supported without error.

The netc-blk-ctrl driver is used to configure Integrated Endpoint
Register Block (IERB) and Privileged Register Block (PRB) of NETC.
For i.MX platforms, it is also used to configure the NETCMIX block.
The IERB contains registers that are used for pre-boot initialization,
debug, and non-customer configuration. The PRB controls global reset
and global error handling for NETC. The NETCMIX block is mainly used
to set MII protocol and PCS protocol of the links, it also contains
settings for some other functions.
Note the IERB configuration registers can only be written after being
unlocked by PRB, otherwise, all write operations are inhibited. A warm
reset is performed when the IERB is unlocked, and it results in an FLR
to all NETC devices. Therefore, all NETC device drivers must be probed
or initialized after the warm reset is finished.

This reverts commit 431be621c6cbc72efd1d45fa36686a682cbb470a.
Section 3.3 of Reduced Gigabit Media Independent Interface (RGMII)
Version 2.0 (4/1/2002) details that a PHYs using a ~2ns internal delay
are referred to as RGMII-ID. This internal delay is optional.
Page 147-148 of the Marvell Doc. No. MV-S107146-U0 Rev. F details
timings of the RX/TX delays. We see that with the TX/RX_CLK delay
enabled, our RX/TX_CTL signal is shifted w.r.t CLK to reflect the delay
added.
In 431be62 there is no timing difference between RGMII and RGMII-ID, and
so programmers wanting to explicitly set their PHY to RGMII will find
that delay added anyway. This could throw off timing if that internal
delay is undesired.
We should be handling all 4 possible RGMII cases of PHY_INTERFACE_MODE:
RGMII, RGMII_ID, RGMII_TXID, and RGMII_RXID. Reverting 431be62
implements this.
See also m88e1111_config_init_rgmii_delays in the equivalent driver in
Linux (drivers/net/phy/marvell.c), which does not set these delays in
RGMII mode.
68e6eca was tested out on an 88E1512 PHY in RGMII-ID mode. This
reversion has been tested by myself on an 88E1518 in RGMII-ID mode. This
patch affects boards using this driver in "rgmii" mode, as the internal
delay will no longer be enabled. Namely kikwood-nsa310s.
