Date: Wed, 27 Feb 2013 15:28:14 -0800 From: Stephen Boyd <sboyd@...eaurora.org> To: linux-arm-kernel@...ts.infradead.org Cc: linux-kernel@...r.kernel.org, linux-arm-msm@...r.kernel.org, Barry Song <baohua.song@....com>, Kukjin Kim <kgene.kim@...sung.com>, Linus Walleij <linus.walleij@...aro.org>, Rob Herring <rob.herring@...xeda.com>, Russell King <linux@....linux.org.uk>, Sascha Hauer <kernel@...gutronix.de>, Shiraz Hashim <shiraz.hashim@...com>, Srinidhi Kasagar <srinidhi.kasagar@...ricsson.com>, Stephen Warren <swarren@...dotorg.org>, Tony Lindgren <tony@...mide.com> Subject: [PATCHv2] ARM: Push selects for TWD/SCU into machine entries The TWD and SCU configs are selected by default as long as MSM_SCORPIONMP is false and/or MCT is false. Implementing the logic this way certainly saves lines in the Kconfig but it precludes those machines which select MSM_SCORPIONMP or MCT from participating in the single zImage effort because when those machines are combined with other SMP capable machines the TWD and SCU are no longer selected by default. Push the select out to the machine entries so that we can compile these machines together and still select the appropriate configs.
