It will most likely fail to boot with u-boot versions that do not support replacing memory configuration in device tree and without CONFIG_ARM_ATAG_DTB_COMPAT enabled. In other words, the memory setup from dts is used only if both of the following are true: - CONFIG_ARM_ATAG_DTB_COMPAT is disabled - u-boot does not modify memory setup in device tree passed to the kernel Best regards, -- Tomasz Figa Samsung Poland R&D Center SW Solution Development, Linux Platform -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
