The goal for sandbox is to test all U-Boot code\nwhere it is practical to do so.\n\nRegards,\nSimon","headers":{"Return-Path":"","X-Original-To":"incoming@patchwork.ozlabs.org","Delivered-To":"patchwork-incoming@bilbo.ozlabs.org","Authentication-Results":["ozlabs.org;\n\tspf=none (mailfrom) smtp.mailfrom=lists.denx.de\n\t(client-ip=81.169.180.215; helo=lists.denx.de;\n\tenvelope-from=u-boot-bounces@lists.denx.de;\n\treceiver=)","ozlabs.org;\n\tdkim=fail reason=\"signature verification failed\" (2048-bit key;\n\tunprotected) header.d=google.com header.i=@google.com\n\theader.b=\"Xy4St1Rm\"; \n\tdkim=fail reason=\"signature verification failed\" (1024-bit key;\n\tunprotected) header.d=chromium.org header.i=@chromium.org\n\theader.b=\"JrHL790p\"; dkim-atps=neutral"],"Received":["from lists.denx.de (dione.denx.de [81.169.180.215])\n\tby ozlabs.org (Postfix) with ESMTP id 3y0pGQ3DPKz9s7F\n\tfor ;\n\tMon, 25 Sep 2017 12:40:14 +1000 (AEST)","by lists.denx.de (Postfix, from userid 105)\n\tid 0E546C221EF; Mon, 25 Sep 2017 02:28:00 +0000 (UTC)","from lists.denx.de (localhost [IPv6:::1])\n\tby lists.denx.de (Postfix) with ESMTP id 92E25C221B9;\n\tMon, 25 Sep 2017 02:27:28 +0000 (UTC)","by lists.denx.de (Postfix, from userid 105)\n\tid 0FE8EC22197; Mon, 25 Sep 2017 02:14:33 +0000 (UTC)","from mail-qt0-f175.google.com (mail-qt0-f175.google.com\n\t[209.85.216.175])\n\tby lists.denx.de (Postfix) with ESMTPS id E5F80C21C8F\n\tfor ; Mon, 25 Sep 2017 02:14:27 +0000 (UTC)","by mail-qt0-f175.google.com with SMTP id q8so5550863qtb.5\n\tfor ; Sun, 24 Sep 2017 19:14:27 -0700 (PDT)","by 10.200.37.200 with HTTP; Sun, 24 Sep 2017 19:14:05 -0700 (PDT)"],"X-Spam-Checker-Version":"SpamAssassin 3.4.0 (2014-02-07) on lists.denx.de","X-Spam-Level":"","X-Spam-Status":"No, score=-0.0 required=5.0 tests=RCVD_IN_DNSWL_NONE,\n\tRCVD_IN_MSPIKE_H3, RCVD_IN_MSPIKE_WL,\n\tT_DKIM_INVALID autolearn=unavailable\n\tautolearn_force=no version=3.4.0","DKIM-Signature":["v=1; a=rsa-sha256; c=relaxed/relaxed; d=google.com;\n\ts=20161025; \n\th=mime-version:sender:in-reply-to:references:from:date:message-id\n\t:subject:to:cc;\n\tbh=16vtVrw7FvyNybOMuYtbBM1feK4ecl1XqsmVw8wJnSw=;\n\tb=Xy4St1RmwZ3R8NLILFW/78N3+nIv+C3aHicfeh5kBkWMu+20GoJm/+vcSh5vRgvCd7\n\t1JTs2ADmy7f/tv1uBppX5zI1kPoVBihGm4aeNCRQ57keUqUcJ60vkszpNuUuSsPX/k6D\n\t/5bgkDXk11ECGVOfPF2gP98Li/V/cxrcLtpYvohbBhY/2kID6WGzd6XNw0KEJUzUjGM4\n\tBuKpKYN0+3NugAoW7N2eZVvl2g+H0d4Mb+tzkOWQHOWcOen2lKNnJn2ZDPqTf7S4wod6\n\tAch4tzeo+PD3HPBhW1Ng9h70KteDkZExf81UFEEQMzWpgxG4c2FjxzTj+ep5LaMITjVp\n\tSh9A==","v=1; a=rsa-sha256; c=relaxed/relaxed; d=chromium.org;\n\ts=google; \n\th=mime-version:sender:in-reply-to:references:from:date:message-id\n\t:subject:to:cc;\n\tbh=16vtVrw7FvyNybOMuYtbBM1feK4ecl1XqsmVw8wJnSw=;\n\tb=JrHL790pGIRJZCMUec9plNj8KDDuA7Y5t2IiY+rqRa4AmnC4DAll6f5j05ETbdxYG5\n\t4dYGsKjRwYmQdkunPHF/eDYpa/6rgQJlWyXIFpmUUvFj6ic/syM5n4rhzEcP9AayjCW8\n\tc7GOGz+Nql3dCAR7JOCQJtwIsDzi7B50dUt7I="],"X-Google-DKIM-Signature":"v=1; a=rsa-sha256; c=relaxed/relaxed;\n\td=1e100.net; s=20161025;\n\th=x-gm-message-state:mime-version:sender:in-reply-to:references:from\n\t:date:message-id:subject:to:cc;\n\tbh=16vtVrw7FvyNybOMuYtbBM1feK4ecl1XqsmVw8wJnSw=;\n\tb=ZAFk/akd8/KtK/2b368XjEr+7LUMp8I9HjC13t7TvO7UVBLxHH3jrqDjaNybsA3w6A\n\t1xghyhjT3vgmYuMSjXxHRgs4Z8XBOeEwuPp45Z8avGoUb9v/+NQsYasiHPvE+BU8pQyT\n\tdKqan69jug6uGm+DXOyrClFHFSCTMoE4xWcGJwNO+vH+v13NrBSjr5/MXVuxvRr9dPyW\n\tTCmOyJkfGNknqsszF8ziU7d9VOhmOI9paI+xHND1+3lyUKg3HoAVTriCkGS46y7rPiu9\n\tFunQ1xTnkMxcEbighQOuzKVh4lQ2PN2LgWFS32JjQ4djK4EaHnSiZEz8YzPOuvDYcoDL\n\tgMug==","X-Gm-Message-State":"AHPjjUiqTDjyjLByqeXyeDmUwddneuahWvD55/lkq7/3vLokkCwvH/kI\n\t2a/yB9brQTRc96wM97Yp+wL08DDto1TRdTVXD12wqD5j","X-Google-Smtp-Source":"AOwi7QBvPuoOIcSwuxs8AClWQemf54rVA581z7pf7BbJ0lUGpfqjdS8EnYHMkXgHDiMoND3vWSh7fPbmZkB4cTK9KgY=","X-Received":"by 10.237.35.238 with SMTP id k43mr9220081qtc.214.1506305666623; \n\tSun, 24 Sep 2017 19:14:26 -0700 (PDT)","MIME-Version":"1.0","In-Reply-To":"","References":"<20170913220546.19560-1-robdclark@gmail.com>\n\t<20170913220546.19560-16-robdclark@gmail.com>\n\t<3b11aa60-c191-cad4-d566-fc273bd42883@suse.de>\n\t\n\t\n\t","From":"Simon Glass ","Date":"Sun, 24 Sep 2017 22:14:05 -0400","X-Google-Sender-Auth":"Ckz5PLeMctxfP__0aGN97emKEUI","Message-ID":"","To":"Rob Clark ","Cc":"Heinrich Schuchardt ,\n\tU-Boot Mailing List ,\n\tPeter Jones ","Subject":"Re: [U-Boot] [PATCH v3 15/21] efi_loader: add bootmgr","X-BeenThere":"u-boot@lists.denx.de","X-Mailman-Version":"2.1.18","Precedence":"list","List-Id":"U-Boot discussion ","List-Unsubscribe":",\n\t","List-Archive":"","List-Post":"","List-Help":"","List-Subscribe":",\n\t","Content-Type":"text/plain; charset=\"utf-8\"","Content-Transfer-Encoding":"base64","Errors-To":"u-boot-bounces@lists.denx.de","Sender":"\"U-Boot\" "}}]
