This patch cleans up some coding style related issues in the mtk_wtd
driver to make this driver comply again with the U-Boot coding style

The only minimal functional change is that the timeout parameter is now

mtk_wdt_set_timeout(), preserving the original value.

This adds support for slave serial programming, in addition to the
previously supported slave SelectMAP mode. There are two ways that this
can be used:
-Using the clk and wdata callbacks in order to write image data one bit
at a time using pure bit-banging. This works, but is rather painfully
slow with typical image sizes.
-By specifying the wbulkdata callback instead, the image loading process
can be offloaded to SPI hardware. In this mode the clk and wdata
callbacks do not need to be specified. This allows the image to be
loaded much faster, taking only a few seconds with even relatively large
images.
Slave serial programming has been tested on the Kintex-7 series of
FPGAs.

The Texas Instrument's System Control Interface (TI-SCI) Message Protocol
is used to communicate to the System Controller from various compute
processors to invoke specific services provided by the firmware running
on the System Controller.
Add a common processor control interface header file that can be used by
multiple remoteproc drivers. The helper functions within this header file
abstract the various TI SCI protocol ops for the remoteproc drivers, and
allow them to request the System Controller to be able to program and
manage various remote processors on the SoC. The common macros required

In the case of the tsec network driver, so far there has been no
mainline user of DM_ETH where the DT bindings get used.
In the case of the mdio bus, it looks like the "fsl,tsec-mdio" string
was made up for the documentation, but there is no mainline code that
parses the "compatible" property anyway.
In both cases, there are no DT blobs that contain the old strings.
So change the documentation to "fsl,etsec2" for the Ethernet ports and
"fsl,etsec2-mdio" for the MDIO buses, which are strings that Linux also
uses, at least for LS1021A. More compatible strings can be added once
other (PowerPC) SoCs are migrated to DM_ETH.
The current ls1021a.dtsi doesn't match what was documented for the MDIO
buses anyway (the "compatible" is "gianfar" currently). This will be

macb.h provides macros for reading/setting bitfields,
in macb registers and descriptors. use that instead
of redefining them in the source file.

Few registers and bits were added by Cadence and
they were not updated in the headers.
Take the latest definitions as defined in Linux
header (5.1) that also includes some comments
about existing registers.
One register was improperly named (UR), fix that.

This driver is used for MDIO muxes driven over I2C. This is currently
used on Freescale LS1028A QDS board, on which the physical MDIO MUX is
controlled by an on-board FPGA which in turn is configured through I2C.

Using 'phy_connect' instead of 'phy_find_by_mask' and 'phy_connect_dev'
both deduplicates code and adds support for 'fixed-link'.

Ethernet interfaces using serial protocols go through the serdes block
integrated in the SoC. This is accessed over dedicated internal MDIOs
which are part of the Ethernet PCI functions. Set up serdes at _start,
along with other protocol specific port/MAC configuration.
MDIO code is shared with enetc_mdio, read/write functions are exported
from fsl_enetc_mdio for this reason.

Adds a driver for the MDIO interface currently integrated in LS1028A SoC.
This MDIO interface is shared by multiple ethernet interfaces and is
presented as a stand-alone PCI function on the SoC ECAM.
Ethernet has a functional dependency on MDIO, for simplicity there is a
single config option for both.
