instead of having access to the main memory. In that case egress packets
must be copied into that memory for transmission and pointers to that

Some code may want to read reg values from DT, but from nodes that aren't
associated with DM devices, so using dev_get_addr_index() isn't
appropriate. In this case, fdtdec_get_addr_size_*() are the functions to
use. However, "translation" (via the chain of ranges properties in parent
nodes) may still be desirable. Add a function parameter to request that,
and implement it. Update all call sites to default to the original

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.

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.

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.
