f1dd05bc34 net: dm: Remove warning about EEPROM provided MAC address
Similar to patch 821fec0ceb ("net: remove scary warning about EEPROM
provided MAC address") this removes the somewhat awkward "warning" on
boards using DM_ETH:
In many parts of the computing world having a unique MAC address
sitting in some on-NIC storage is considered the normal case.

If there is a properly provided MAC address (either from ROM or from DT),
remove the warning to not scare the user unnecessarily.

0914011310 command: Remove the cmd_tbl_t typedef
We should not use typedefs in U-Boot. They cannot be used as forward

Drop the typedef and rename the struct to remove the _s suffix which is

5fe419ef2a net: Add eth phy generic driver for shared MDIO
For dual ethernet controllers, the HW design may connect ETH phys to
one MDIO ports. So two different ethernet drivers have to share MDIO bus.
Since two ethernet drivers are independent, we can't ensure their probe
order.

To resolve this problem, introduce an eth phy generic driver and uclass.

After eth-uclass binds, we search the mdio node and binds the phy node
with the eth-phy-generic driver.

When one eth driver get its phy device, the parent of phy device will
probe prior than phy device. So this ensure the eth driver ownes the
MDIO bus will be probed before using its MDIO.

336d4615f8 dm: core: Create a new header file for 'compat' features
At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.

16cdc2daa0 net: tftp: Fix too small block size
Commit b618b37076 ("net: Convert CONFIG_TFTP_BLOCKSIZE to Kconfig")
accidentally set the default *option* TFTP block size to 512 bytes, even
though the comment in the code says that this is a terrible choice. Most
boards didn't define the symbol before, so they got the default block size
of 1468 bytes before, but now use 512 bytes, which is also the fallback.
This leads to both abysmal performance and a lot of hashes printed
on the screen (one character for every 5K), which is both annoying and
slow over serial links.

Set the default block size in Kconfig back to the value it had before.

This improves TFTP performance from 2.8 MB/s to 6.9 MB/s on a Pine64.

change, the return value of eth_initialize() will also change to the

spl_net to decide whether there are any devices to boot from. So
returning only available devices is also more correct in that case.
