From 72573543b5b9f788b46fb9e7ab3372cfeba8d25f Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Fri, 2 Nov 2012 06:56:13 +0000 Subject: ARM: tegra: enable 8-bit SD slots in board files Harmony contains an SD slot with all 8 bits routed. This allows plugging in an eMMC-chip-in-SD-form-factor. Seaboard/Springbank/Ventana/AC100 all have an eMMC chip with all 8 bits hooked up. Now that the U-Boot eMMC code fully supports 8-bit operation, initialize those ports as 8-bit instead of 4-bit to improve performance. Whistler was already registering its ports as 8-bit. TrimSlice doesn't have any 8-bit ports. I don't have any Avionic Design boards nor the Colibri board to test with.
