The timeout test in axi_dma_init is not correct due to the
post-decrement used on the timeout variable which will mean timeout is
not 0 if the timeout occurs. Make the timeout variable an int instead of
a u32 and then test for timeout being -1.

In mvpp2_probe the code attempts to get a value for "gop-port-id" and

cannot be negative. Change the test to port->gop_id.

get_timer returns a ulong value representing system time in ms.
On a 64-bit system, this ulong value is 64 bits long. However,
the driver stores it in a 32-bit unsigned integer, which overflows
after 49 days up time, causing the driver to get an incorrect time.
Replace the unsigned int variable with a ulong type to properly store
the value returned by get_timer.

The Auto Negotiation procedure between two Ethernet PHYs consists of
determining the best commonly supported parameters among Speed,
Duplex Mode and Flow Control.
The time taken for this procedure is not only dependent on the local
PHY used, but also on the link-partner PHY.
While a timeout can be specified in the form of a "CONFIG" on the basis
of the local PHY present on the device, since the timeout also depends
on the link-partner PHY, it might be necessary to modify the timeout.
To avoid rebuilding the bootloader for a given device, just because it
may be connected to various link-partner PHYs, each with a different
timeout, introduce an environment variable named "phy_aneg_timeout" and
override "CONFIG_PHY_ANEG_TIMEOUT" with "phy_aneg_timeout".

Transmission of short packets does not work good for XFI (GDM2) and
HSGMII (GDM3) interfaces. The issue can be solved with:
- padding of short packets to 60 bytes
- setting of PAD_EN bit in the corresponding REG_GDM_FWD_CFG(n)
register.
The issue should present for the lan switch (GDM1) as well, but it does
does not appear due to unknown reason.

ARCH_DMA_MINALIGN is 64 for ARMv7a/ARMv8a architectures, but RX/TX
descriptors are 32 bytes long. So they may not be aligned on an
ARCH_DMA_MINALIGN boundary. In case of RX path, this may cause the
following problem
1) Assume that a packet has arrived and the EVEN rx descriptor has been
updated with the incoming data. The driver will invalidate and check
the corresponding rx descriptor.
2) Now suppose the next descriptor (ODD) has not yet completed.
Please note that all even descriptors starts on 64-byte boundary,
and the odd ones are NOT aligned on 64-byte boundary.
Inspecting even descriptor, we will read the entire CPU cache line
(64 bytes). So we read and sore in CPU cache also the next (odd)
descriptor.
3) Now suppose the next packet (for the odd rx descriptor) arrived
while the first packet was being processed. So we have new data
in memory but old data in cache.
4) After packet processing (in arht_eth_free_pkt() function) we will
cleanup the descriptor and put it back to rx queue.
This will call flush_dcache_range() function for the even descriptor,
so the odd one will be flushed as well (it is in the same cache line).
So the old data will be written to the next rx descriptor.
5) We get a freeze. The next descriptor is empty (so the driver is
waiting for packets), but the hardware will continue to receive
packets on other available descriptors. This will continue until
the last available rx descriptor is full. Then the hardware will
also freeze.
The problem will be solved if the previous descriptor will be put back
to the queue instead of the current one.
If the current descriptor is even (starts on a 64-byte boundary),
then putting the previous descriptor to the rx queue will affect
the previous cache line. To be 100% ok, we must make sure that the
previous and the one before the previous descriptor cannot be used
for receiving at this moment.
If the current descriptor is odd, then the previous descriptor is on
the same cache line. Both (current and previous) descriptors are not
currently in use, so issue will not arrise.
WARNING: The following restrictions on PKTBUFSRX must be held:
* PKTBUFSRX is even,
* PKTBUFSRX >= 4.
The bug appears on 32-bit airoha platform, but should be present on
64-bit as well.

The dma_map_single() function calls one of the functions
* invalidate_dcache_range(),
* flush_dcache_range().
Both of them expect that 'vaddr' is aligned to the ARCH_DMA_MINALIGN
boundary. Unfortunately, RX/TX descriptors are 32-byte long. Thus they
might not be aligned to the ARCH_DMA_MINALIGN boundary. Data flushing
(or invalidating) might do nothing in this case.
The same applies to dma_unmap_single() function.
In the TX path case the issue might prevent package transmission (filled
TX descriptor was not flushed).
To fix an issue a special wrappers for
* dma_map_single(),
* dma_unmap_single()
functions were created. The patch fix flushing/invalidatiog for the
RX path as well.

Turn the current cache operation macros into static functions to improve
compiler coverage checking. This does change the driver behavior slightly,
the driver now expects those cache operation functions to be available on
all architectures on which it is used. This should pose no problem, as the
driver is only used on 32bit and 64bit ARM, which both have those operations.

Update the ICSSG PRU Ethernet driver to read PRU/RTU/TXPRU firmware names
from the Device Tree using the "firmware-name" property, instead of relying
on the hard-coded firmware names. The firmware names are parsed during
prueth_probe() and stored in the prueth->firmwares for each slice. The
driver now uses these dynamically loaded names when starting the PRU cores.
This change improves flexibility and allows firmware selection to be
controlled via the device tree, making the driver more adaptable to
different platforms and firmware configurations.

Romain Gantois <romain.gantois@bootlin.com> says:

- Describing the MAC<->PHY link and DP83867 PHY accurately in the device

- Enabling the RGMII1 pinmux configuration
- Enabling the DP83867 driver
These changes are all applied in patch 2.
Patch 1 enables excluding the DP83867 driver from SPL. This is done to
