2021-01-05dtoc: Tidy up src_scan testsSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dtoc: Move src_scan tests to a separate fileSimon Glass
Move the tests related to scanning into their own class, updating them to avoid using dtb_platdata as a pass-through. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dtoc: Split source-code scanning to a separate fileSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dtoc: Drop dm_populate_phandle_data()Simon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dtoc: Output nodes in orderSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dtoc: Allow specifying the base directory for testsSimon Glass
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(). Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dtoc: Add the method for each command to OutputFileSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dtoc: Rename dt-platdata.c to dt-plat.cSimon Glass
Use this new name to be consistent with the rest of U-Boot, which talks about 'plat' for the platform data, which is what this file holds. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dtoc: Add a header comment to each generated fileSimon Glass
It is currently fairly obvious what the two generated files are for, but this will change as more are added. It is helpful for readers to describe the purpose of each file. Add a header commment field to OutputFile and use it to generate a comment at the top of each file. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dtoc: Run tests using test_utilSimon Glass
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). Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05concurrencytest: Fix Python3 warningSimon Glass
This gives a warning in some situations: File "tools/dtoc/../concurrencytest/concurrencytest.py", line 95, in do_fork stream = os.fdopen(c2pread, 'rb', 1) File "/usr/lib/python3.8/os.py", line 1023, in fdopen return io.open(fd, *args, **kwargs) RuntimeWarning: line buffering (buffering=1) isn't supported in binary mode, the default buffer size will be used Fix this by dropping the line-buffer parameter. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dm: Rename U_BOOT_DRIVER_ALIAS to DM_DRIVER_ALIASSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dm: Rename DM_GET_DRIVER() to DM_DRIVER_GET()Simon Glass
In the spirit of using the same base name for all of these related macros, rename this to have the operation at the end. This is not widely used so the impact is fairly small. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dm: Rename DM_GET_DEVICE() to DM_DRVINFO_GET()Simon Glass
This does not get a device (struct udevice *) but a struct driver_info * so the name is confusing. Rename it accordingly. Since we plan to have several various of these macros, put GET at the end instead of the middle, so it is easier to spot the related macros. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dm: Rename U_BOOT_DEVICE() to U_BOOT_DRVINFO()Simon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05Makefile: Invoke dtoc only onceSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dtoc: Add an 'all' commandSimon Glass
With upcoming changes, dtoc will output several files for different of-platdata components. Add a way to output all ava!ilable files at once ('all'), to the appropriate directories, without needing to specify each one invidually. This puts the commands in alphabetical order, so update the tests accordingly. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dtoc: Allow outputing to multiple filesSimon Glass
Implement the 'output directory' feature, allowing dtoc to write the output files separately to the supplied directories. This allows us to handle the struct and platdata output in one run of dtoc. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dtoc: Allow providing a directory to write files toSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dtoc: Test the stdout outputSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dtoc: Use None to mean stdoutSimon Glass
At present dtoc uses '-' internally to mean that output should go to stdout. This is not necessary and None is more convenient. Update it. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dtoc: Tidy up pylint warnings in testSimon Glass
Tidy up this file to reduce the number of pylint warnings. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dm: core: Add logging when lists_bind_fdt() failsSimon Glass
It is useful to see the error code when this fails. Add logging for this function. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dm: core: Allow the uclass list to moveSimon Glass
At present the uclass list head is in global_data. This is convenient but with the new of-platdata we need the list head to be declared by the generated code. Change this over to be a pointer. Provide a 'static' version in global_data to retain the current behaviour. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dm: core: Split out scanning code to dm_scan()Simon Glass
Move the code related to scanning for devices to bind, into a new function. This will make it easier to skip this step with the new of-platdata improvements. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dm: core: Rename device node to indicate it is privateSimon Glass
To avoid having people accidentally access this member, add a trailing underscore. Also remove it when of-platdata is enabled, since it is not used. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dm: core: Access device ofnode through functionsSimon Glass
At present ofnode is present in the device even if it is never used. With of-platdata this field is not used, so can be removed. In preparation for this, change the access to go through inline functions. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dm: core: Use dev_has_ofnode() instead of dev_of_valid()Simon Glass
We have two functions which do the same thing. Standardise on dev_has_ofnode() since there is no such thing as an 'invalid' ofnode in normal operation: it is either null or missing. Also move the functions into one place. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
2021-01-05dm: core: Rename dev_has_of_node() to dev_has_ofnode()Simon Glass

At present flags are stored as part of the device. In preparation for storing them separately, change the access to go through inline functions. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dm: core: Rename sqq to seq_Simon Glass

2021-01-05dm: core: Split out alloc code into a new functionSimon Glass

2021-01-05x86: coral: Remove unwanted nodes from SPL/TPLSimon Glass
Some devices are not needed in SPL/TPL. For TPL this causes the generation of unnecessary of-platadata structs. Make some adjustments to fix this. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05x86: apl: Adjust how the UART gets its platform dataSimon Glass
At present this driver calls malloc() to start a new platform data structure, fills it in and tells driver model to use it. We want to avoid malloc, particularly with the new version of of-platdata. Create a new struct which encompasses both the dtd struct and the ns16550 one, to avoid this. Unfortunately we must copy the data into the right place for the ns16550 driver. Add some comments about this. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05x86: sysreset: Move priv/plat structs to headersSimon Glass

2021-01-05x86: apl: Use struct spi_nor instead of struct spi_flashSimon Glass
This construct effectively uses struct spi_nor due to a #define in spi-nor.h so we may as well use that struct here. This allows dtoc to parse it correctly. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05spi: Tweak a few strange SPI NOR features for of-platdataSimon Glass
The #define of one struct to another has been around for a while. It confuses dtoc and makes it think that struct spi_flash does not exist. Make a few changes to improve things while we wait for migration to be completed: - Move the 'struct spi_flash' to column 1 so dtoc scans it - Remove the #define when compiling dt-platdata.c - Update the strange mtd_get/set_of_node() functions - Use struct spi_nor in the drivers, so dtoc sees the correct struct Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05spi: Tidy up get/set of device nodeSimon Glass
This code is a bit odd in that it only reads and updates the livetree version of the device ofnode. This means it won't work with flattree. Update the code to work as it was presumably intended. Signed-off-by: Simon Glass <sjg@chromium.org>

2021-01-05sandbox: Update dts files to reduce SPL sizeSimon Glass
At present there are require a few devices in the devicetree which are not actually used in SPL. This will cause problems with the new of-platdata, since it will try to instantiate devices which are not compiled into U-Boot. Update the devicetree to remove these devices from SPL.
