From 166ef1e90ce404a6470a1c4910a1e84404379b86 Mon Sep 17 00:00:00 2001 From: Gong Qianyu Date: Mon, 25 Jan 2016 15:16:06 +0800 Subject: armv8/ls1043aqds: add QSPI support in SD boot QSPI and IFC are pin-multiplexed on LS1043A. So we use ls1043aqds_sdcard_ifc_defconfig to support IFC in SD boot and ls1043aqds_sdcard_qspi_defconfig to support QSPI in SD boot.
