2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass
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. Move the compatibility features into a separate header file.

These functions are used by code outside the network support, so move them to lib/ to be more accessible.

2019-12-09net: tftp: Fix too small block sizeAndre Przywara
Commit b618b3707633 ("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.

2019-12-09net: eth-uclass: ignore unavailable devicesMichael Walle
device_probe() may fail in which case the seq_id will be -1. Don't display these devices during startup. While this is only a cosmetic change, the return value of eth_initialize() will also change to the actual number of available devices. The return value is only used in spl_net to decide whether there are any devices to boot from. So returning only available devices is also more correct in that case.

This works around limitations with using the DT node name on devices such as Armada-8040, which integrates two cp100 cores, both featuring MDIOs at the same relative offsets and with the same DT node names. The concept was originally proposed by Marvell as a custom property called mdio-name specific to Marvell driver.

In order for the device to use the proper MAC address, which can have been configured in the environment prior to the device being registered, ensure that the MAC address is written after the device has been probed. For devices that are registered before the network stack is initialized, this is already done during eth_initialize(). If the Ethernet device is on a bus that is not initialized on early boot, such as PCI, the device is not available at the time eth_initialize() is called, so we need the MAC address programming to also happen after probe.
