From ae2044d8b30bf82fef5550497a0d4315edf6b62e Mon Sep 17 00:00:00 2001 From: Xie Xiaobo Date: Mon, 3 Oct 2011 12:18:39 -0700 Subject: [PATCH] powerpc/mpc8536ds: Add eSPI support for MPC8536DS 1. The SD_DATA[4:7] signals are shared with the SPI chip selects on 8536DS, so don't set MPC85xx_PMUXCR_SD_DATA that config eSDHC data bus-width to 4-bit and enable SPI signals. 2. Add eSPI controller and SPI-FLASH definition.
