[Alison Wang] Thanks for your reply. 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
