8.5. Release v2025.02.0

8.5.1. Environment Auto-Probe

A new magic variable global.env.autoprobe now controls whether barebox will automatically probe known block devices for a GPT barebox environment partition if no environment was specified by other means.

The variable defaults to 0 (false) if CONFIG_INSECURE is disabled.

The most secure option remains disabling CONFIG_ENV_HANDLING completely or, starting with v2025.10.0, using the security policy support for runtime access control.

8.5.2. Zynq 7000

The MMC controller numbering is now fixed: mmc0 & mmc1 for &sdhci0 and &sdhci1 respectively.
