Add a KUnit test that confirms a DTB has been loaded, i.e. there is a root node, and that the of_have_populated_dt() API works properly. We skip the test when CONFIG_OF_EARLY_FLATREE=n because in that case we know architecture code hasn't called unflatten_(and_copy_)?device_tree() which would populate some sort of root node.

unflatten_device_tree() now ensures that the 'of_root' node is populated with the root of a default empty devicetree. Remove the unittest code that created 'of_root' if it was missing. Verify that 'of_root' is valid before attempting to attach the testcase-data subtree. Remove the unittest code that unflattens the unittest overlay base if architecture is UML because that is always done now. Signed-off-by:

Call this function unconditionally so that we can populate an empty DTB on platforms that don't boot with a firmware provided or builtin DTB. There's no harm in calling unflatten_device_tree() unconditionally here. If there isn't a non-NULL 'initial_boot_params' pointer then unflatten_device_tree() returns early.

When enabling CONFIG_OF on a platform where 'of_root' is not populated by firmware, we end up without a root node. In order to apply overlays and create subnodes of the root node, we need one. Create this root node by unflattening an empty builtin dtb. If firmware provides a flattened device tree (FDT) then the FDT is unflattened via setup_arch(). Otherwise, the call to unflatten(_and_copy)?_device_tree() will create an empty root node. We make of_have_populated_dt() return true only if the DTB was loaded by firmware so that existing callers don't change behavior after this patch. The call in the of platform code is removed because it prevents overlays from creating platform devices when the empty root node is used. [sboyd@kernel.org: Update of_have_populated_dt() to treat this empty dtb as not populated. Drop setup_of() initcall] Signed-off-by:

We want to populate an empty DT whenever CONFIG_OF is enabled so that overlays can be applied and the DT unit tests can be run. Make unflatten_and_copy_device_tree() stop printing a warning if the 'initial_boot_params' pointer is NULL. Instead, simply copy the dtb if there is one and then unflatten it. If there isn't a DT to copy, then the call to unflatten_device_tree() is largely a no-op, so nothing really changes here.

There is no reason to use RESERVEDMEM_OF_DECLARE() as the initialization hook just saves off the base address and size. Use of RESERVEDMEM_OF_DECLARE() is reserved for non-driver code and initialization which must be done early. For qbman, retrieving the address and size can be done in probe just as easily.
