I agreed with you about creating a new multi_v7_lpae_defconfig. In multi_v7_lpae_defconfig, I need to add the following CONFIG_XX to support LS1021A based on multi_v7_defconfig. CONFIG_ARM_LPAE=y CONFIG_VMSPLIT_2G=y CONFIG_BLK_DEV_RAM=y CONFIG_BLK_DEV_RAM_SIZE=256000 CONFIG_GIANFAR=y CONFIG_REALTEK_PHY=y CONFIG_I2C_IMX=y CONFIG_SPI_FSL_DSPI=y CONFIG_IMX2_WDT=y CONFIG_REGULATOR_DEBUG=y CONFIG_REGULATOR_VIRTUAL_CONSUMER=y CONFIG_SOUND=y CONFIG_SND=y CONFIG_SND_SOC=y CONFIG_SND_SOC_FSL_SAI=y CONFIG_SND_SOC_SGTL5000=y CONFIG_SND_SIMPLE_CARD=y CONFIG_FSL_EDMA=y CONFIG_CLK_QORIQ=y What's your suggestion? If it's ok, I will send a patch about multi_v7_lpae_defconfig. Best Regards, Alison Wang
