Subject: [PATCH 1/2] Makefile.lib: introduce lwl-y for lowlevel code
Date: Wed, 20 Feb 2013 13:56:15 +0100 [thread overview]
Message-ID: <1361364976-8949-1-git-send-email-plagnioj@jcrosoft.com> (raw)
The lowlevel code is expected to be present only ONCE
in PBL is enabled otherwise in barebox
This fix the module support with PBL and allow to reduce the size of barebox
by drop the lowlevell init in barebox as the compiler does not discard it
