Subject: lib: Split panic functions out of vsprintf.c
X-Git-Tag: v2016.01-rc3~20^2~5
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=2b22a99c65c437891ab88703dff25e256f78c21f;p=u-boot

lib: Split panic functions out of vsprintf.c

To allow panic and panic_str to still be used when using tiny-printf,
split them out into their own file which gets build regardless of what
printf implementation is used.
