non-dt build The pl330 device instances and associated platform data is required only for non-device-tree builds. With device tree, all of this information is obtained from the device tree.

Do we need _really_ EXYNOS4_DEV_DMA here? How about to use like following? +obj-$(!CONFIG_OF) += dma.o If any problems, let me know. Thanks. Best regards, Kgene. -- Kukjin Kim [off-list ref], Senior Engineer, SW Solution Development Team, Samsung Electronics Co., Ltd.
