Normally dtoc outputs to a file but it also offers a way to write output to stdout. At present the test for that does not actually check that the output is correct. Add this to the test.

This uses a member variable to hold the expected text, so it can be used in muitiple places.

At present dtoc writes only a single file on each invocation. U-Boot writes the two files it needs by separate invocations of dtoc. Since dtoc now scans all U-Boot driver source, this is fairly slow (about 1 second per file).

It would be better if dtoc could write all the files at once.

In preparation for this, add a way to specify an output directory for the files.

Update the Makefile to run dtoc only once, generating all required files. This saves time since there is a lot of processing in each invocation of dtoc.

We already have a variable for the object files to build, so use that instead of repeating the same filenames. Add a C version of this also, for the same reason.

This makes it easier to add new C files (generated by dtoc) to the build later, as needed.

The current macro is a misnomer since it does not declare a device directly. Instead, it declares driver_info record which U-Boot uses at runtime to create a device.

The distinction seems somewhat minor most of the time, but is becomes quite confusing when we actually want to declare a device, with of-platdata. We are left trying to distinguish between a device which isn't actually device, and a device that is (perhaps an 'instance'?)

It seems better to rename this macro to describe what it actually is. The macros is not widely used, since boards should use devicetree to declare devices.

Rename it to U_BOOT_DRVINFO(), which indicates clearly that this is declaring a new driver_info record, not a device.

We use the U_BOOT_ prefix (i.e. U_BOOT_DRIVER) to declare a driver but in every other case we just use DM_. Update the alias macros to use the DM_ prefix.

We could perhaps rename U_BOOT_DRIVER() to DM_DRIVER(), but this macro is widely used and there is at least some benefit to indicating it us a U-Boot driver, particularly for code ported from Linux. So for now, let's keep that name.

Use the standard function for running tests and reported results. This allows the tests to run in parallel, which is a significant speed-up on most machines (e.g. 4.5 seconds -> 1.5s on mine).

Rather than the if/else construct, update OutputFile with the method to call to process each command. This is easier to maintain as the number of commands increases.

Rename generate_tables to generate_plat since it better describes what is being generated ('plat' is the U-Boot name for platform data).

With this, each output method needs to have the same signature. Store the output structures in a member variable instead of using parameters, to accomplish this.

The base directory of U-Boot, where the source is, it currently calculated from the directory of the dtb_platdata.py script. If this is installed elsewhere that will not work. Also it is inconvenient for tests.

Add a parameter to allow specifying this base directory.

To test this, pass a temporary directory with some files in it and check that they are passed to scan_driver().

Previously we had to worry about nodes being output before those that they depended on, thus causing build errors. So the current algorithm is careful to output nodes in the right order.

We now use a different method for outputting phandles that does not involve pointers. Also we plan to add a 'declarations' header file to declare all drivers as 'extern'.

Update the code to drop the dependency checking and output in a simple loop. This makes the output easier to follow since drivers are in order of thier indices (0, 1, ...), which is also the order it appears in in the linker list.

This has not been needed since parent information was added and we started using indicies for references to other drivers instead of pointers. It was kept around in the expectation that it might be needed later.

However with the latest updates, it doesn't seem likely that we'll need this in the foreseeable future.

Drop dm_populate_phandle_data() from dtoc and driver model.

Before expanding the scanning features any more, move this into a separate file. This will make it easier to maintain in the future. In particular, it reduces the size of dtb_platdata.py and allows us to add tests specifically for scanning, without going through that file.

The pieces moved are the Driver class, the scanning code and the various naming functions, since they mostly depend on the scanning results.

So far there is are no separate tests for src_scan. These will be added as new functionality appears.

This introduces no functional change.

Some of these tests don't actually check anything. Add a few more checks to complete the tests.

Also add a simple scan test that does the basics.

At present we simply record the name of a driver parsed from its implementation file. We also need to get the uclass and a few other things so we can instantiate devices at build time. Add support for collecting this information. This requires parsing each driver file.

We should ignore anything in the .git directory or any of the build-sandbox, etc. directories created by 'make check'. These can confuse dtoc. Update the code to ignore these.

Uclasses can have per-device private / platform data so dtoc needs to scan these drivers. This allows it to find out the size of this data so it can be allocated a build time.

Add a parser for uclass information, similar to drivers. Keep a dict of the uclasses that were found.

It is confusing to have the test files in the same places as the implementation. Move them into a separate directory.

Add a helper function for test_dtoc, to avoid repeating the same path.

It is convenient to attach drivers, etc. to nodes so that we can use the Node object as the main data structure in this module.

Add a function which adds the new properties, along with documentation.

Add logic to assign property values to nodes as required by dtoc. The references allow nodes to refer to each other in C code. The macros used by dtoc are not yet defined in driver model. They will be added along with the actual driver model implementation.

U-Boot operates in several phases, typically TPL, SPL and U-Boot proper. The latter does not use dtoc.

In some rare cases different drivers are used for two phases. For example, in TPL it may not be necessary to use the full PCI subsystem, so a simple driver can be used instead.

This works in the build system simply by compiling in one driver or the other (e.g. PCI driver + uclass for SPL; simple_bus for TPL). But dtoc has no way of knowing which code is compiled in for which phase, since it does not inspect Makefiles or dependency graphs.

So to make this work for dtoc, we need to be able to explicitly mark drivers with their phase. This is done by adding an empty macro to the driver. Add support for this in dtoc.

def test_uclass_scan(self):

Typically dtoc can detect the header file needed for a driver by looking for the structs that it uses. For example, if a driver as a .priv_auto that uses 'struct serial_priv', then dtoc can search header files for the definition of that struct and use the file.

In some cases, enums are used in drivers, typically with the .data field of struct udevice_id. Since dtoc does not support searching for these, add a way to tell dtoc which header to use. This works as a macro included in the driver definition.

Now that we have the alias information we can assign a sequence number to each device in the uclass. Store this in the node associated with each device.

This requires renaming the sandbox test drivers to have the right name. Note that test coverage is broken with this patch, but fixed in the next one.

The device for the root node is normally bound by driver model on init. With devices being instantiated at build time, we must handle the root device also.

Add support for processing the root node, which may not have a compatible string.

Add Kconfig options to support build-time device instantiation. When fully implemented, this will allow dtoc to create U-Boot devices (i.e. struct udevice records) at build time, thus reducing code space in SPL.

For now this defaults to off, but will be enabled when the rest of the implementation is in place.

This file is not used when instantiating devices. Update dtoc to skip generating its contents and just add a comment instead.

Also it is useful to see the driver name and parent for each device. Update the file to show that information, to avoid updating the same tests twice.
