3078e03516 net: mvpp2: fix second cp110 initialization
Since the mdio code got upstreamed it is not possible
to activate network ports on CP110 Master and Slave.

The problem is in mvpp2_base_probe which is called for each
CP110 and it initializes the buffer area for descs and rx_buffers.

This should only happen once though and the bd space is actually
set to 0 after the first run of the function.

This leads to an error when the second CP110 tries the initialization
again and disables all network ports on this CP110.

This patch adds a static variable to check if the buffer area is
initialized only once globally.

117a52e238 net: smc911x: Properly handle EEPROM MAC address
When compiled as a DM_ETH driver, the scm911x driver was reading the MAC
address from the optional EEPROM storage, but failed to copy this to the
platdata struct. Since it was also missing a definition of the
read_rom_hwaddr() function, the generic Ethernet code was dismissing
this MAC address, falling back to a random address or denying to start
at all.

Add an implementation of .read_rom_hwaddr, and refactor the function
reading the ROM address to be called by all interested parties.

This fixes MAC address issues when using the driver in DM_ETH "mode".

a718a5d0f4 net: dwc_eth_qos: update the compatible supported for STM32
Update the compatible associated with the STM32 MPU glue
in the DWC ethernet driver.

The supported compatible is the specific "st,stm32mp1-dwmac"
as indicated in Linux binding
Documentation/devicetree/bindings/net/stm32-dwmac.txt
and not the "snps,dwmac-4.20a" only used to the select IP
version.

This glue is implemented in Linux kernel in:
drivers/net/ethernet/stmicro/stmmac/dwmac-stm32.c

For information in stm32mp151.dtsi, the 2 compatibles are
supported:

ethernet0: ethernet@5800a000 {
	compatible = "st,stm32mp1-dwmac", "snps,dwmac-4.20a";

The current code is horribly complex. Both the RX and TX buffer

descriptors are part of the private data.

56c4046038 spi: Convert CONFIG_DM_SPI* to CONFIG_$(SPL_TPL_)DM_SPI*
This change allows more fine tuning of driver model based SPI support in
SPL and TPL. It is now possible to explicitly enable/disable the DM_SPI
support in SPL and TPL via Kconfig option.

Before this change it was necessary to use:
    /* SPI Flash Configs */
    #if defined(CONFIG_SPL_BUILD)
    #undef CONFIG_DM_SPI
    #undef CONFIG_DM_SPI_FLASH
    #undef CONFIG_SPI_FLASH_MTD
    #endif

in the ./include/configs/<board>.h, which is error prone and shall be
avoided when we strive to switch to Kconfig.

The goal of this patch:

Provide distinction for DM_SPI support in both U-Boot proper and SPL (TPL).
Valid use case is when U-Boot proper wants to use DM_SPI, but SPL must
still support non DM driver.

Another use case is the conversion of non DM/DTS SPI driver to support
DM/DTS. When such driver needs to work in both SPL and U-Boot proper, the
distinction is needed in Kconfig (also if SPL version of the driver
supports OF_PLATDATA).

In the end of the day one would have to support following use cases (in
single driver file - e.g. mxs_spi.c):

- U-Boot proper driver supporting DT/DTS
- U-Boot proper driver without DT/DTS support (deprecated)
- SPL driver without DT/DTS support
- SPL (and TPL) driver with DT/DTS (when the SoC has enough resources to
  run full blown DT/DTS)
- SPL driver with DT/DTS and SPL_OF_PLATDATA (when one have constrained
  environment with no fitImage and OF_LIBFDT support).

Some boards do require SPI support (with DM) in SPL (TPL) and some only
have DM_SPI{_FLASH} defined to allow compiling SPL.

This patch converts #ifdef CONFIG_DM_SPI* to #if CONFIG_IS_ENABLED(DM_SPI)
and provides corresponding defines in Kconfig.

89b5bd54c1 net: fec: Allow the PHY node to be retrieved
As we move towards driver model, it is required to let the FEC driver
know how to properly deal with an Ethernet PHY subnode in the device tree.

For example:

 &fec {
 	pinctrl-names = "default";
 	pinctrl-0 = <&pinctrl_microsom_enet_ar8035>;
	phy-handle = <&phy>;
 	phy-mode = "rgmii-id";
 	phy-reset-duration = <2>;
 	phy-reset-gpios = <&gpio4 15 GPIO_ACTIVE_LOW>;
 	status = "okay";

	mdio {
		#address-cells = <1>;
		#size-cells = <0>;

		phy: ethernet-phy@0 {
			reg = <0>;
			qca,clk-out-frequency = <125000000>;
		};
	};
 };

Currently the PHY node pointer is incorrectly associated with the
Ethernel controller instead of the PHY node itself.

This causes the PHY properties, such as "qca,clk-out-frequency" in
the example above to not get parsed.

Fix this problem by populating the phy_of_node node.

    This patch fixes the clock frequency configuration for ATH8030 and

thought dev->priv. Also remove the unnecessary check for lp being
non-NULL, since it is always NULL at this point.

60074d9d3e net: pcnet: Wrap devbusfn into private data
Instead of using eth_device priv for this PCI devbusfn, free it
so it could be used for driver private data, and wrap devbusfn
into those driver private data.

Note that using the name dev for the variable is a trick left for
later, when DM support is in place, so dm_pci_virt_to_mem() can be
used with minimal ifdeffery.

246d2bfcf2 net: pcnet: Move private data allocation to initialize
The private data allocation does not have to be done every time the
NIC is initialized at run time, move the allocation to initialize
function, which means it will be done only once when the driver
starts.

1c38c36eb9 net: pcnet: Simplify private data allocation
The current code is horribly complex. Both the RX and TX buffer
descriptors are 16 bytes in size, the init block is 32 bytes in
size, so simplify the code such that the entire private data of
the driver are allocated cache aligned and the RX and TX buffer
descriptors are part of the private data.

This removes multiple malloc calls and cache flushes.
