From a19adf8d86e822eba502486524127595372c85f6 Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Wed, 8 Mar 2017 10:19:10 +0100 Subject: [PATCH] ARM: dts: bcm283x: switch from &sdhci to &sdhost sdcard access with the sdhost controller is faster. Read access (dd with 64k blocks on rpi2): CONFIG_MMC_SDHCI_IPROC: 11-12 MB/s CONFIG_MMC_BCM2835: 19-20 MB/s Differences on write access are pretty much in the noise.
