This reverts commit ed6251187afabf811a5fd49a44ebd61c53c7b378.

Superseded by "cmd: pxe_utils: Limit fdtcontroladdr usage to non-fitImage"
which is less heavy-handed approach and retains part of the original
behavior for non-fitImage.

The original patch is use phy_get_interface_by_name to set interface.
The new patch is use dev_read_phy_mode to replace it.

With the change here, all extlinux.conf files with only "KERNEL
/fitImage" don't work anymore. One common example of this would be those
files generated by thee Poky/OE WIC bootimg-partition bootloader
partition generator.

Both PCS/PMA PHY and the external PHY need to have a valid link status
in order to have Ethernet traffic. Check and wait this status at
setup_phy() so that we could diagnose if there is a PHY issue.

If we bridge an external PHY to Xilinx's PCS/PMA PHY and would like to
get and set the real status of the PHY facing the external world. Then
we should phy_connect() to the external PHY instead of the PCS/PMA one.
Thus, we add a pcs-handle DT entry, which have been merged in Linux, and
leave the configuration of it to the driver itself.

Unlike Linux, where the PCS/PMA PHY is managed by phylink, managing the
PCS/PMA PHY is only internal to the driver in U-Boot. The PCS/PMA PHY
pressents only when the phy-mode is configured as SGMII or 1000Base-X,
so it is always 1 Gbps and full-duplex and we may skip passing link
information out.

Add a driver for the Intel XWAY GbE PHY:
 - configure RGMII using dt phy-mode and standard delay properties
 - use genphy_config

The rx descriptor list is in cached memory, and there may be multiple
descriptors per cache-line. After reclaim_rx_buffers marks a descriptor
as unused it does a cache flush, which causes the entire cache-line to
be written to memory, which may override other descriptors in the same
cache-line that the controller may have written to.

The fix skips freeing descriptors that are not the last in a cache-line,
and if the freed descriptor is the last one in a cache-line, it marks
all the descriptors in the cache-line as unused.
This is similarly to what is done in drivers/net/fec_mxc.c

In my case this bug caused tftpboot to fail some times when other
packets are sent to u-boot in addition to the ongoing tftp (e.g. ping).
The driver would stop receiving new packets because it is waiting
on a descriptor that is marked unused, when in reality the descriptor
contains a new unprocessed packet but while freeing the previous buffer
descriptor & flushing the cache, the driver accidentally marked the
descriptor as unused.

Add new desc_per_cacheline property which lets a platform run RX descriptor
cleanup after every power-of-2 - 1 received packets instead of every packet.
This is useful on platforms where (axi_bus_width EQOS_AXI_WIDTH_n * DMA DSL
inter-descriptor word skip count + DMA descriptor size) is less than cache
line size, which necessitates packing multiple DMA descriptors into single
cache line.

In case of TX descriptors, this is not a problem, since the driver always
does synchronous TX, i.e. the TX descriptor is always written, flushed and
polled for completion in eqos_send().

In case of RX descriptors, it is necessary to update their status in bulk,
i.e. after the entire cache line worth of RX descriptors has been used up
to receive data.
