I think we need to add && RESET_CONTROLLER to that || branch of the depends on to fix that. ARCH_TEGRA selects RESET_CONTROLLER explicitly, so the COMPILE_TEST branch needs to mirror that. Either that, or I suppose we could add the depends on RESET_CONTROLLER explicitly to TEGRA_MC, or perhaps even select it (although that could cause conflicts down the road, but should be fine right now because RESET_CONTROLLER doesn't have any other dependencies right now). Not sure what to do about that orphaned __reservedmem_of_table section. Maybe all we need to do is to select OF_RESERVED_MEM from TEGRA210_EMC_TABLE? Let me to a few test builds. Thierry
