From 16e43f354dfbec24e6151338fa199cf5bb551648 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Beno=C3=AEt=20Th=C3=A9baudeau?= Date: Mon, 13 Aug 2012 07:28:16 +0000 Subject: fsl_esdhc: Remove cache snooping for i.MX MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The cache snooping feature of Freescale's eSDHC IP is not available on i.MX, so disable it globally for this architecture. This avoids setting no_snoop for all i.MX boards, and it prevents setting a reserved bit of a reserved register if fsl_esdhc_mmc_init() is used on i.MX, like in arch/arm/cpu/armv7/imx-common/cpu.c/cpu_mmc_init(). Since no_snoop was only used on i.MX, get rid of it BTW.
