Please see

Instead of having CONFIG_ARCH_DMA_ADDR_T_64BIT=y in the defconfig, I
guess selecting it from Kconfig makes more sense:
diff --git a/arch/arm/mach-imx/Kconfig b/arch/arm/mach-imx/Kconfig
index 573536f1bb73..bb417e73af0f 100644
--- a/arch/arm/mach-imx/Kconfig
+++ b/arch/arm/mach-imx/Kconfig
@@ -563,6 +563,7 @@ config SOC_LS1021A
select HAVE_ARM_ARCH_TIMER
select PCI_DOMAINS if PCI
select ZONE_DMA if ARM_LPAE
+ select ARCH_DMA_ADDR_T_64BIT
help
This enables support for Freescale LS1021A processor.
