From: Paul Gortmaker Date: Tue, 18 Jun 2013 17:01:10 +0000 (+0000) Subject: MIPS: Delete Wind River ppmc eval board support. X-Git-Tag: next-20130628~112^2~34 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=54c4bc2ad55eb082f1a61114549d08514c27d08a;p=karo-tx-linux.git MIPS: Delete Wind River ppmc eval board support. This board has been EOL for many years now; lets not burden people doing build coverage and other tree wide work with working on essentially dead files.
