From: Benoît Thébaudeau Date: Thu, 11 Apr 2013 09:35:58 +0000 (+0000) Subject: arm: Remove support for smdk6400 X-Git-Tag: v2013.04-rc3~1^2~24 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=52587f1ef8643142c818d0ebf581a46942ee1954;p=u-boot arm: Remove support for smdk6400 The migration of boards from Makefile to boards.cfg was due for v2012.03, but smdk6400 did not follow, and it does not build, so move it to scrapyard. It will still be possible to restore it from the Git history before fixing it.
