On UML builds, of_address.c fails to compile: ../drivers/of/address.c:873:2: error: implicit declaration of function ‘ioremap’ [-Werror=implicit-function-declaration] This is due to CONFIG_OF now being user selectable. Add a dependency on HAS_IOMEM to OF_ADDRESS in order to fix this. Signed-off-by: Rob Herring <robh@kernel.org> Cc: Grant Likely <grant.likely@linaro.org>

On some platforms, the device tree can be manipulated at runtime.

While this option is selected automatically on such platforms, you
