[PATCH 1/3] environment: Use accessor functions for default environment path

[Sascha Hauer]

default_environment_path only exists when CONFIG_ENV_HANDLING is enabled.
Boards would have to #ifdef this if they wanted to use
default_environment_path. Use accessor functions instead which can
be ifdeffed on a single place.

[PATCH 3/3] net: phy: Add static inline wrapper for phy_register_fixup_for_uid

[Sascha Hauer]

Boards register a fixup for a phy without checking if phy support
is enabled. To fix compilation without phy support add a static
inline wrapper for phy_register_fixup_for_uid.
