Subject: Move debug and logging support to a separate header
X-Git-Tag: v2018.01-rc2~52
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=0e98b0a65092d6573eb17d07e04455f9cf545b21;p=u-boot

Move debug and logging support to a separate header

Before adding new features, move these definitions to a separate header
to avoid further cluttering common.h.
