[U-Boot-Users] [PATCH v2] Memory footprint optimizations

Bartlomiej Sieka tur at semihalf.com
Fri Apr 18 12:39:23 CEST 2008


As suggested by Wolfgang Denk:
- image printing functions:
  - remove wrappers
  - remove indentation prefix from functions' signatures
- merge getenv_verify and getenv_autostart into one parametrized function
