a744a284e3 net: phy: Add support for ethernet-phy-id with gpio reset
Ethernet phy like dp83867 is using strapping resistors to setup PHY
address. On Xilinx boards strapping is setup on wires which are connected
to SOC where internal pull ups/downs influnce phy address. That's why there
is a need to setup pins properly (via pinctrl driver for example) and then
perform phy reset. I can be workarounded by reset gpio done for mdio bus
but this is not working properly when multiply phys sitting on the same
bus. That's why it needs to be done via ethernet-phy-id driver where dt
binding has gpio reset per phy.

DT binding is available here:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/net/ethernet-phy.yaml

The driver is are reading the vendor and device id from valid phy node
using ofnode_read_eth_phy_id() and creating a phy device.
Kconfig PHY_ETHERNET_ID symbol is used because not every platform has gpio
support.

90ab7fafb6 mmc: zynq_sdhci: Add support for dynamic configuration
Add support for dynamic configuration which will takes care of
configuring the SD secure space configuration registers using firmware
APIs, performing SD reset assert and deassert.

High level sequence:
  - Check for the PM dynamic configuration support, if no error proceed
    with SD dynamic configurations(next steps) otherwise skip the dynamic
    configuration.
  - Put the SD Controller in reset.
  - Configure SD Fixed configurations.
  - Configure the SD Slot Type.
  - Configure the BASE_CLOCK.
  - Configure the 8-bit support.
  - Bring the SD Controller out of reset.

In the above steps, apart from the Fixed configurations, remaining all
configurations are dynamic and they will be read from devicetree.

And also remove hardcoded secure register writes, as dynamic sd config
support is added.

3adc17f60b lib: div64: Add support for round up of div64_u64
Most of the frequencies are not rounded up to a proper number.
When we need to devide these frequencies to get a number for example
frequency in Mhz, we see it as one less than the actual intended value.
Ex: If we want to get Mhz from frequency 199999994hz, we will calculate
it using div64_u64(199999994, 1000000) and we will get 199Mhz in place
of 200Mhz.

Add a macro DIV64_U64_ROUND_UP for rounding up div64_u64. This is taken
from linux 'commit 68600f623d69("mm: don't miss the last page because of
round-off error")'.

c12f9d2e54 drivers: serial: Make sure we really return a serial device
The stdout-path property in the device tree does not necessarily
point at a serial device. On machines such as the Apple M1 laptops
where the serial port isn't easy to access and users expect to see
console output on the integrated display stdout-path may point at
the device tree node for the framebuffer for example.

If stdout-path does not point at a node for a serial device, the
serial_check_stdout() will not find a bound device and will drop
down into code that attempts to use lists_bind_fdt() to bind a
device anyway. However, that fallback code does not check that
the uclass of the device is UCLASS_SERIAL. So if stdout-path points
at the framebuffer instead of the serial device it will return a
UCLASS_VIDEO device. Since the code that calls this function
expects the returned device to be a UCLASS_SERIAL device, U-Boot
will crash as soon as it attempts to send output to the console.

Add a check here to verify that the uclass of the bound device
really is UCLASS_SERIAL. If it isn't, serial_check_stdout() will
return an error and serial_find_console_or_panic() will use the
serial device with sequence number 0 as the console and all is fine.

817e153fe5 watchdog: rti_wdt: Add 10% safety margin to clock frequency
When running against RC_OSC_32k, the watchdog may suffer from running
faster than expected, expiring earlier. The Linux kernel adds a 10%
margin to the timeout calculation by slowing down the read clock rate
accordingly. Do the same here, also to have comparable preset values
for both drivers.

Along this, fix the name of the local var holding to frequency - in Hz,
not kHz.

8b82a3a7fe arm64: zynqmp: Enable DP driver for SOMs
The main reason is to send pmufw cfg overlay from U-Boot to PMUFW to enable
access to DP. Overlay is sent when cls command is called and for that IP
has to be enabled in carrier cards.
And IP needs to be also enabled in SOM dt because with DTB reselection new
DT is not parsed in pre reloc U-Boot instance. It is called from board_f
via embedded_dtb_select(). That's why bind function is not able to allocate
memory and it ends up with error:
"Video device 'display@fd4a0000' cannot allocate frame buffer memory
-ensure the device is set up before relocation"

To avoid this situation DP is placed also to SOM where bind function is
called and frame buffer memory is allocated and just reused after DTB
reselection. Result is the same. There could be a problem in Linux with
different DP configurations but that's need to be solved there because
console should be on from u-boot already.

a3efa53c01 arm64: zynqmp: Use assigned-clock-rates for setting up clock in SOM
With limited low level configuration done via psu-init only IPs connected
on SOM are initialized and configured. All IPs connected to carrier card
are not initialized. There is a need to do proper reset, pin configuration
and also clock setting.
The patch targets the last part which is setting up proper clock for USBs
and SDs.
Also setup proper bus width for SD cards.

c36dc2449b arm64: zynqmp: Move usb hub from i2c to usb node
Based on upstream discussion based on link below usb hub should be placed
to usb node directly as child node. Based on this Linux driver was updated
and the same change should be also reflected in kv260 board.

d7b5cc89d3 microblaze: Do not place u-boot to reserved memory location
Microblaze can also have reserved space in DT which u-boot has to avoid to
placing self to that location. The same change was done in Zynqmp by commit
ce39ee28ec ("zynqmp: Do not place u-boot to reserved memory location").

This feature was tested with this memory description on kc705:

	memory {
		device_type = "memory";
		reg = <0x80000000 0x40000000>;
	};

	reserved-memory {
		#address-cells = <1>;
		#size-cells = <1>;
		ranges;

		alloc@b00000000 {
			reg = <0xb0000000 0x10000000>;
			no-map;
		};

		alloc@a8000000 {
			reg = <0xa8000000 0x00010000>;
			no-map;
		};
	};

And in U-Boot log you can check u-boot relocation address and reserved
locations.

Remove private xpm_configobject[] and use zynqmp_pmufw_node() which
provides the same functionality.
Also add debug messages for easier debugging.
