15c49df8d4 phy: make phy_connect_fixed work with a null mdio bus
It is utterly pointless to require an MDIO bus pointer for a fixed PHY
device. The fixed.c implementation does not require it, only
phy_device_create. Fix that.

f9d3b31883 net: xilinx: axi_emac: Fix dma descriptors for 64bit and compilation warnings
There are compilation warnings showing up when we compile AXI ethernet
driver for 64bit architectures. Fix them, so that it works on both 32
and 64 bit architectures.

DMA descriptors are not taking care of 64bit addresses. To fix it,
change axidma_bd members as below:

next		==>	next_desc
reserverd1	==>	next_desc_msb
phys		==>	buf_addr
reserverd2	==>	buf_addr_msb

and update next_desc and buf_addr with lower 32 bits of the addresses,
update next_desc_msb and buf_addr_msb with upper 32 bits of the 64bit
addresses.

- fix mailaddress from Holger

Series-changes: 2
- add comments from Qiang Zhao:
  - add device node documentation
  - I did not drop the dm_qe_uec_phy.c and use drivers/net/fsl_mdio.c
    because using drivers/net/fsl_mdio.c leads in none existent
    udevice mdio@3320
    instead boards with DM ETH support should use now this
    driver.
- remove RFC tag

Commit-notes:

- I let the old none DM based implementation in code
  so boards should work with old implementation.
  This Code should be removed if all boards are converted
  to DM/DTS.

- add the DM based qe uec driver under drivers/net/qe

- Therefore copied the files uccf.c uccf.h uec.h from
  drivers/qe. So there are a lot of Codingstyle problems
  currently. I fix them in next version if this RFC
  patch is OK or it needs some changes.

- The dm based driver code is now under drivers/net/qe/dm_qe_uec.c
  Used a lot of functions from drivers/qe/uec.c

- seperated the PHY specific code into seperate file
  drivers/net/qe/dm_qe_uec_phy.c

ac458dc823 bcmgenet: fix DMA buffer management
This commit fixes a serious issue occurring when several network
commands are run on a raspberry pi 4 board: for instance a "dhcp"
command and then one or several "tftp" commands. In this case,
packet recv callbacks were called several times on the same packets,
and send function was failing most of the time.

note: if the boot procedure is made of a single network
command, the issue is not visible.

The issue is related to management of the packet ring buffers
(producer / consumer) and DMA.
Each time a packet is received, the ethernet device stores it
in the buffer and increments an index called RDMA_PROD_INDEX.
Each time the driver outputs a received packet, it increments
another index called RDMA_CONS_INDEX.

Between each pair of network commands, as part of the driver
'start' function, previous code tried to reset both RDMA_CONS_INDEX
and RDMA_PROD_INDEX to 0. But RDMA_PROD_INDEX cannot be written from
driver side, thus its value was actually not updated, and only
RDMA_CONS_INDEX was reset to 0. This was resulting in a major
synchronization issue between the driver and the device. Most
visible behavior was that the driver seemed to receive again the
packets from the previous commands (e.g. DHCP response packets
"received" again when performing the first TFTP command).

This fix consists in setting RDMA_CONS_INDEX to the same
value as RDMA_PROD_INDEX, when resetting the driver.

The same kind of fix was needed on the TX side, and a few variables
had to be reset accordingly (c_index, tx_index, rx_index).

The rx_index and tx_index have only 256 entries so the bottom 8 bits
must be masked off.

b75d8dc564 treewide: convert bd_t to struct bd_info by coccinelle
The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:

  It's a **mistake** to use typedef for structures and pointers.

Besides, using typedef for structures is annoying when you try to make
headers self-contained.

Let's say you have the following function declaration in a header:

  void foo(bd_t *bd);

This is not self-contained since bd_t is not defined.

To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>

  #include <asm/u-boot.h>
  void foo(bd_t *bd);

Then, the include direcective pulls in more bloat needlessly.

If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:

  struct bd_info;
  void foo(struct bd_info *bd);

Right, typedef'ing bd_t is a mistake.

I used coccinelle to generate this commit.

The semantic patch that makes this change is as follows:

  typedef bd_t;

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";
	...

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.

    The masks in priv->clk_25m_reg and priv->clk_25m_mask are one-bits-set
    for the values that comprise the fields, not zero-bits-set.

    This patch fixes the clock frequency configuration for ATH8030 and
    ATH8035 Atheros PHYs by removing the erroneous "~".

    To reproduce this bug, configure the PHY  with the device tree binding
    "qca,clk-out-frequency" and remove the machine specific PHY fixups.

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.

TI specific file that can register all TI PHYs that are defined in the
defconfig.  The ti_phy_init file will contain all TI PHYs initialization
so that only phy_ti_init can be called from the framework.

In addition to the above the config flag for the DP83867 needs to be changed
in the Kconfig and dependent defconfig files. The config flag that was
used for the DP83867 was also generic in nature so a more specific
config flag for the DP83867 was created.

99ac86187d net: sun8i_emac: Add support for the H6 variant
The H6 EMAC is very similar to the H3 variant, except that it uses the
same pinmux as R40. Add support for it.

abdbefba2a net: sun8i_emac: Use consistent clock bitfield definitions
While the R40 uses a different register for EMAC clock configuration
than other chips, the register has a very similar layout. Reuse the
existing bitfield definitions in this file, since they match.

This allows the driver to compile on the H6 platform, where the
CCM_GMAC_CTRL definitions are not present.

9c9f3fc162 net: ks8851: Receive one packet per recv call
Instead of reading out the entire FIFO and possibly overwriting U-Boot
memory, read out one packet per recv call, pass it to U-Boot network
stack, and repeat. It is however necessary to cache RXFC value, because
reading that one out clears it.
