Subject: env: Rename getenv_hex(), getenv_yesno(), getenv_ulong()
X-Git-Tag: v2017.09-rc3~80
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=bfebc8c965e41d62dc6355d09bdd63ca57011b99;p=u-boot

env: Rename getenv_hex(), getenv_yesno(), getenv_ulong()

We are now using an env_ prefix for environment functions. Rename these
for consistency. Also add function comments in common.h.
