Second set of u-boot-at91 features for the 2022.04 cycle:

This small feature set includes few changes for sama7g5 and sama7g5ek:
turn blue led on at boot, changes required for the Rev4 of the board,
better sync with the Linux DT with regards to the new DT nodes.

dbf500b557 configs: at91: sama7g5ek: enable CONFIG_PHANDLE_CHECK_SEQ
CONFIG_PHANDLE_CHECK_SEQ will allow different sequence number for nodes
that have the same name, but they are different.
In sama7g5ek case, there are multiple 'i2c@600' nodes which are child
nodes of different parent 'flexcom' nodes.
These are different i2c busses even if the node is the same, and have to be
differentiated.
Without this config, the sequence number 0 is reused for two i2c busses, and
this is something that we have to avoid:

Looking for 'i2c' at 4704, name i2c@600
   - serial0, /ahb/apb/serial@e1824200
   - i2c0, /ahb/apb/flexcom@e181c000/i2c@600

Found seq 0
i2c_post_bind: i2c@600, seq=0

Add Flexcom8 node with required referenced nodes as phandles.
Since Flexcom8 is present in Linux, take the node exactly as-is from Linux.
Some nodes are referenced in Linux as phandles, the dma and the gic.
Add them as well to the file, even if they are unused by Uboot.
This is a step towards having the U-boot DT equivalent with the DT in Linux.

eab18b3b06 net: fsl: Fix busy flag polling register
NXP's mEMAC reference manual, Chapter 6.5.5 "MDIO Ethernet Management
Interface usage", specifies to poll the BSY (0) bit in the CFG/STAT
register to wait until a transaction has finished, not bit 31 in the
data register.

In the Linux kernel, this has already been fixed in commit 26eee0210ad7
("net/fsl: fix a bug in xgmac_mdio").

This patch changes the register in the fman_mdio and fsl_ls_mdio
drivers.

As the MDIO_DATA_BSY define is no longer in use, this patch also removes
its definition from the fsl_memac header.

6372ece6e8 net: dsa: sja1105: fix device id detection
The sja1105_check_device_id() function contains logic to work without
changing the device tree on reworked boards, one of which I have (the
NXP LS1021A-TSN normally has a SJA1105T, but I have a version with a
resoldered SJA1105Q which is pin compatible). This logic is taken from
the Linux driver.

However this logic gets shortcircuited in U-Boot by an earlier check for
the exact device ID specified in the device tree. So the reworked board
does not probe the SJA1105Q switch. Remove this duplicated logic and let
the automatic device ID detection do its job.

0fa4448d51 net: dsa: fix phydev->speed being uninitialized for the CPU port fixed PHY
If the DSA API is going to allow drivers to do things such as:

- phy_config in dsa_ops :: port_probe
- phy_startup in dsa_ops :: port_enable

then it would actually be good if the ->port_probe() method would
actually be called in all cases before the ->port_enable() is.

Currently this is true for user ports, but not true for the CPU port,
because the CPU port does not have a udevice registered for it (this is
all part of DSA's design). So the current issue is that after
phy_startup has finished for the CPU port, its phydev->speed is an
uninitialized value, because phy_config() was never called for the
priv->cpu_port_fixed_phy, and it is precisely phy_config() who copies
the speed into the phydev in the case of the fixed PHY driver.

So we need to simulate a probing event for the CPU port by manually
calling the driver's ->port_probe() method for the CPU port.

c2969792c4 cmd: pxe_utils: sysboot: add label override support
This will allow consumers to choose a pxe label at runtime instead of
having to prompt the user. One good use-case for this, is choosing
whether or not to apply a dtbo depending on the hardware configuration.
e.g: for TI's AM335x EVM, it would be convenient to apply a particular
dtbo only when the J9 jumper is on PRUSS mode. To achieve this, the
pxe menu should have 2 labels, one with the dtbo and the other without,
then the "pxe_label_override" env variable should point to the label with
the dtbo at runtime only when the jumper is on PRUSS mode.

This change can be used for different use-cases and bring more
flexibilty to consumers who use sysboot/pxe_utils.

if "pxe_label_override" is set but does not exist in the pxe menu,
the code should fallback to the default label if given, and no failure
is returned but rather a warning message.

a2f1482fc0 efi_loader: Get rid of kaslr-seed if EFI_RNG_PROTOCOL is installed
U-Boot, in some occasions, injects a 'kaslr-seed' property on the /chosen
node. That would be problematic in case we want to measure the DTB we
install in the configuration table, since it would change across reboots.

The Linux kernel EFI-stub completely ignores it and only relies on
EFI_RNG_PROTOCOL for it's own randomness needs (i.e the randomization
of the physical placement of the kernel). In fact it (blindly) overwrites
the existing seed if the protocol is installed. However it still uses it
for randomizing it's virtual placement.
So let's get rid of it in the presence of the RNG protocol.

It's worth noting that TPMs also provide an RNG.  So if we tweak our
EFI_RNG_PROTOCOL slightly and install the protocol when a TPM device
is present the 'kaslr-seed' property will always be removed, allowing
us to reliably measure our DTB.

226fce6108 phy: Track power-on and init counts in uclass
On boards using the RK3399 SoC, the USB OHCI and EHCI controllers share
the same PHY device instance. While these controllers are being stopped
they both attempt to power-off and deinitialize it, but trying to
power-off the deinitialized PHY device results in a hang. This usually
happens just before booting an OS, and can be explicitly triggered by
running "usb start; usb stop" in the U-Boot shell.

Implement a uclass-wide counting mechanism for PHY initialization and
power state change requests, so that we don't power-off/deinitialize a
PHY instance until all of its users want it done. The Allwinner A10 USB
PHY driver does this counting in-driver, remove those parts in favour of
this in-uclass implementation.

The sandbox PHY operations test needs some changes since the uclass will
no longer call into the drivers for actions matching its tracked state
(e.g. powering-off a powered-off PHY). Update that test, and add a new
one which simulates multiple users of a single PHY.

The major complication here is that PHY handles aren't deduplicated per
instance, so the obvious idea of putting the counts in the PHY handles
don't immediately work. It seems possible to bind a child udevice per
PHY instance to the PHY provider and deduplicate the handles in each
child's uclass-private areas, like in the CLK framework. An alternative
approach could be to use those bound child udevices themselves as the
PHY handles. Instead, to avoid the architectural changes those would
require, this patch solves things by dynamically allocating a list of
structs (one per instance) in the provider's uclass-private area.
