2017-08-16env: Rename getenv/_f() to env_get()Simon Glass
We are now using an env_ prefix for environment functions. Rename these two functions for consistency. Also add function comments in common.h. Quite a few places use getenv() in a condition context, provoking a warning from checkpatch. These are fixed up in this patch also.

2014-05-29Rename bootretry functions and remove #ifdefsSimon Glass
Add a bootretry_ prefix to these two functions, and remove the need for the #ifdef around everything (it moves to the Makefile). Signed-off-by: Simon Glass <sjg@chromium.org>
2014-05-29Move bootretry code into bootretry.c and clean upSimon Glass
This code is only used by one board, so it seems a shame to clutter up the readline code with it. Move it into its own file. Signed-off-by: Simon Glass <sjg@chromium.org>
