Paul Burton 96cb57c5ea net: pch_gbe: Make 64 bit safe
The pch_gbe driver previously casted pointers to & from unsigned 32 bit
integers in many locations. This breaks the driver on 64 bit systems,
producing streams of compiler warnings about mismatched pointer &
integer sizes and then failing to keep track of addresses correctly at
runtime.

Fix the driver for 64 bit systems by using unsigned longs in place of
the previously used 32 bit integers.

Paul Burton 154bf12f78 net: pch_gbe: Use dm_pci_map_bar to discover MMIO base
Reading the PCI BAR & converting the result to a physical address is not
safe across all architectures. For example on MIPS the virtual:physical
mapping is not 1:1, so we cannot directly make use of the physical
address.

Use the more generic BAR-mapping function dm_pci_map_bar to discover the
MMIO base address, which should work across architectures.

karl beldan 05237f735e net: davinci_emac: Restore the internal MDIO accessors return values
The spatch series converting legacy drivers from miiphy_register to
mdio_register changed the return convention of the davinci_emac internal
MDIO accessors, making the internal code relying on it misbehaving:
no mdiodev get registered and U-Boot crashes when using net cmds in the
context of the old legacy net API.

ATM davinci_emac_initialize and cpu_eth_init don't return a proper value
in that case but fixing them would not avoid the crash.

This change is just a follow-up to the spatch pass, the MDIO accessors
of the mdiodev introduced by the spatch pass retain their proper values.

Chen-Yu Tsai a85ba87dbe net: sun8i_emac: Drop redundant and incorrect setting of syscon register
In sun8i_emac_board_setup, the driver partially configures the syscon
register for H3 EPHY. However, the settings are incomplete, and
completely unusable. The correct settings are later set in
sun8i_emac_set_syscon, but the incorrect CLK_SEL setting persists.

It is incorrect to use CLK_SEL to select 25 MHz, as the SoC does not
have a 25 MHz clock the EPHY can use.

This patch removes the setting of the syscon register in board_setup,
and also moves set_syscon above mdio_init. While mdio_init does not
access the PHY, it is better to have the PHY parameters setup before
the MDIO bus is registered.

Alexey Firago 79887749f8 net: phy: micrel: add support for KSZ886x switches in MIIM mode
This patch adds a phy driver for the Micrel KSZ886x switches.

Similarly to the KSZ8895, SoC MAC is directly connected to the switch
MAC on the switch CPU port, so the link to the switch is always up.

KSZ886x switches can be used in the following configuration modes:
- Unmanaged mode with config stored in external EEPROM
- Managed mode over SPI
- Managed mode over I2C
- Managed mode over mdio/mdc (aka MIIM or SMI)

This patch supports only unmanaged and MIIM modes.

Based on Micrel KSZ886x driver from Linux kernel and
Micrel KSZ8895 driver from U-Boot.

Verified with the KSZ8863MLL.

Stephen Warren dad7b74045 net: rtl8169: fix switching between adapters
The rtl8169 driver uses a global variable to store the register address
of the adapter being operated upon. This is updated to point at the
correct adapter when sending or receiving a packet, or shutting down the
adapter, but not when initializing the adapter. Consequently, switching
between different adapters within the same U-Boot runtime does not work
correctly since the driver programs the wrong registers during
rtl8169_eth_start() -> rtl8169_common_start() -> rtl8169_hw_start().

Note that since rtl8169_eth_stop() does set the global variable, the
second consecutive attempt to use the "new" adapter did work even before
this patch, because each time network usage is shut down, the network
core calls stop, which sets the variable so that the next start does
actually initialize the hardware, and the adapter works.

Equally, rtl8169_eth_probe() calls rtl_init() which sets the global, so
if using only a single device, or if picking the "right" device (based on
probe order) when multiple devices are present, ioaddr will already be set
correctly from the get-go, so the issue does not occur.
