In vsc8514_config there is a while loop for detecting a config failure using a timeout counter with a post-decrement. In the case of a timeout this will result in the loop exiting with timeout == -1 so use that as the test below the loop to detect that the timeout occurred. This issue was found by Smatch.

The Auto Negotiation procedure between two Ethernet PHYs consists of determining the best commonly supported parameters among Speed, Duplex Mode and Flow Control. The time taken for this procedure is not only dependent on the local PHY used, but also on the link-partner PHY. While a timeout can be specified in the form of a "CONFIG" on the basis of the local PHY present on the device, since the timeout also depends on the link-partner PHY, it might be necessary to modify the timeout. To avoid rebuilding the bootloader for a given device, just because it may be connected to various link-partner PHYs, each with a different timeout, introduce an environment variable named "phy_aneg_timeout" and override "CONFIG_PHY_ANEG_TIMEOUT" with "phy_aneg_timeout".

If phy node isn't found in ethernet-phy subnode, try to get it from phy-handle. And when this fails, only then use Ethernet node. This fix results in getting correct phy handle properties for the phy node if defined. Signed-off-by: Naresh Kumar Ravulapalli <nareshkumar.ravulapalli@altera.com>
Romain Gantois <romain.gantois@bootlin.com> says: This is version one of my series which enables Ethernet support on the BBGE board. This requires three main changes: - Describing the MAC<->PHY link and DP83867 PHY accurately in the device tree - Enabling the RGMII1 pinmux configuration - Enabling the DP83867 driver These changes are all applied in patch 2. Patch 1 enables excluding the DP83867 driver from SPL. This is done to avoid size issues when adding the DP83867 driver to the am335x-evm defconfig. Link: https://lore.kernel.org/r/20250626-bbge-ethernet-v1-0-5b544fb1898f@bootlin.com
The DP83867 PHY driver is used by the BeagleBoneGreen Eco board, but adding it to the am335x-evm defconfig causes SPL to overflow its size limits. Add a separate option to enable this driver in SPL, so that it can be enabled in U-Boot without adding unnecessary volume to SPL.

Rename the variable and add ENV_ prefix, so that all configuration options which are related to environment would have an CONFIG_ENV_ prefix. No functional change.
