From cba69eeeaa67d3fb93ec6f3abab1f653abf895a9 Mon Sep 17 00:00:00 2001 From: Ian Campbell Date: Mon, 5 May 2014 11:52:26 +0100 Subject: sunxi: add sun7i cpu, board and start of day support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch adds generic board, start of day and basic build system support for the Allwinner A20 (sun7i) processor. This code will not been compiled until the build is hooked up in a later patch. It has been split out to keep the patches manageable.

It's "correct" in so far as it works (the boards.cfg config stuff #defines things to 1), but I think you are right that it isn't the preferred style. But... > A quick scan through this patch series shows that this define > is not set at all. Perhaps its outdated? Or is it used to support > some other sunxi SoC? Not sure, perhaps it should be removed for > now. ...I had thought that it was to support some other board which wasn't being upstreamed right now, so eventually useful and harmless for now, but I've just checked and it isn't actually used by any of the boards in u-boot-sunxi.git. So rather than fix it to use #ifdef lets drop it. Rather than resend the entire series, here is v5.1 of this patch. > Other than this please add my: > > Reviewed-by: Stefan Roese Thanks! 8<--------------------------------- >From 20704e35a41664de5f516ed0e02981ac06085102 Mon Sep 17 00:00:00 2001 From: Ian Campbell Date: Fri, 7 Mar 2014 04:29:39 +0000 Subject: [PATCH v5.1 7/8] sunxi: mmc support This adds support for the MMC controller on the Allwinner A20 (sun7i) processor.
