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.

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>
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.

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>
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.

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().

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>
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>
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.

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>
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>
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>
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.

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>
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>
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>
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>
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>
At present dtoc uses '-' internally to mean that output should go to
stdout. This is not necessary and None is more convenient. Update it.

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.

At present ofnode is present in the device even if it is never used. With

We have two functions which do the same thing. Standardise on

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.

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>
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
