This does not set the correct value at present. Fix it. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-08binman: Run tests concurrentlySimon Glass
At present the tests run one after the other using a single CPU. This is not very efficient. Bring in the concurrencytest module and run the tests concurrently, using one process for each CPU by default. A -P option allows this to be overridden, which is necessary for code-coverage to function correctly. This requires fixing a few tests which are currently not fully independent. At some point we might consider doing this across all pytests in U-Boot. There is a pytest version that supports specifying the number of processes to use, but it did not work for me.

2018-10-08buildman: dtoc: Suppress unwanted output from testSimon Glass
There are a few test cases which print output. Suppress this so that tests can run silently in the normal case. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-08binman: Fix up removal of temporary directoriesSimon Glass
At present 'make check' leaves some temporary directories around. Part of this is because we call tools.PrepareOutputDir() twice in some cases, without calling tools.FinaliseOutputDir() in between. Fix this. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-08binman: Add a default path to libfdt.pySimon Glass
This module is often available in the sandbox_spl build created by 'make check'. Use this as a default path so that just typing 'binman -t' (without setting PYTHONPATH) will generally run the tests. Signed-off-by: Simon Glass <sjg@chromium.org>

2018-09-28dtoc: Fixed endianness in Prop.GetEmpty()Simon Glass
This should be big endian, since that is what device tree uses. Fix it. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-09-28dtoc: Allow syncing of the device tree back to a fileSimon Glass
At present we require the caller to manually update the device tree using individual calls to libfdt functions. This is not ideal. It would be better if we could make changes using the Python structure and then call a Sync() function to write them back. Add this feature to the Fdt class. Update binman and the tests to match. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-08-08libfdt: Update to latest pylibfdt implementationSimon Glass
The enhanced pylibfdt support in U-Boot needed for binman was a placeholder while upstreaming of this work continued. This is now complete, so bring in the changes and update the tools as needed. There are quite a few changes since we decided to split the implementation into three fdt classes instead of two. The Fdt.del_node() method was unfortunately missed in this process and will be dealt with later. It exists in U-Boot but not upstream. Further syncing of libfdt probably needs to wait until we assess the code-size impact of all the new checking code on SPL and possibly provide a way to disable it.

2018-08-01dtoc: Add a function to obtain a list of phandlesSimon Glass
Add a function which can decode a property containing a list of phandles. This is useful for finding nodes linked to a property. Also provide a way to look up a single phandle and get the Fdt object from a Node. Signed-off-by: Simon Glass <sjg@chromium.org>

2018-08-01binman: Add an entry filled with a repeating byteSimon Glass
It is sometimes useful to have an area of the image which is all zeroes, or all 0xff. This can often be achieved by padding the size of an an existing entry and setting the pad byte for an entry or image. But it is useful to have an explicit means of adding blocks of repeating data to the image. Add a 'fill' entry type to handle this. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-08-01binman: Add support for passing arguments to entriesSimon Glass
Sometimes it is useful to pass binman the value of an entry property from the command line. For example some entries need access to files and it is not always convenient to put these filenames in the image definition (device tree). Add a -a option which can be used like this: -a<prop>=<value> where <prop> is the property to set <value> is the value to set it to Signed-off-by: Simon Glass <sjg@chromium.org>

2018-07-09dtoc: Fix properties with a single zero-arg phandleSimon Glass

2018-07-09dtoc: Fix Fdt.GetNode() to handle a missing nodeSimon Glass

2018-07-09dtoc: Keep track of property offsetsSimon Glass
At present the Fdt class does not keep track of property offsets if they change due to removal of properties. Update the code to handle this, and add a test. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-07-09dtoc: Update fdt tests to increase code coverageSimon Glass

2018-07-09dtoc: Drop use of a local dtb bufferSimon Glass
At present the Fdt class has its own copy of the device tree. This is confusing an unnecessary now that pylibfdt has its own. Drop it and provide access functions to the buffer. This allows us to move the rest of the implementation to use pylibfdt methods instead of directly calling libfdt stubs. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-07-09dtoc: Make use of the new pylibfdt methodsSimon Glass
Now that pylibfdt supports a fuller API we don't need to directly call the libfdt stubs. Update the code to use the Fdt methods instead. Some other cases remain which will be tidied up in a later commit, since they need larger changes. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-07-09dtoc: Update tests to write failures to /tmpSimon Glass
When a test fails due to an output mismatch (e.g. due to a new property being adding to a test file) it is currently hard to update the test to the new output. In particular the tabs in the file are written as \t in the Python tests. To make this easier, write both the expected and actual results to /tmp to allow use of meld, and copying into the test.

2018-07-09dtoc: Add some tests for the fdt moduleSimon Glass
At present this module is tested via the dtoc tests. This is a bit painful since the tests are at a higher level and so failures are more difficult to diagnose. Add some tests that exercise the fdt module directly. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-07-09libfdt: Bring in proposed pylibfdt changesSimon Glass
This provides various patches sent to the devicetree-compiler mailing list to enhance the Python bindings. A final version of this patch may be created once upstreaming is complete, but if it takes too long, this can act as a placeholder. New pylibfdt features: - Support for most remaining, relevant libfdt functions - Support for sequential-write functions Changes are applied to existing U-Boot tools as needed.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2018-01-15dtoc: Allow DTC environment variable to provide path to dtcSimon Glass

2017-09-15dtoc: Support properties containing multiple phandle valuesSimon Glass
At present dtoc has a very simplistic view of phandles. It assumes that a property has only a single phandle with a single argument (i.e. two cells per property). This is not true in many cases. Enhance the implementation to scan all phandles in a property and to use the correct number of arguments (which can be 0, 1, 2 or more) when generating the C code. For the struct definitions, use a struct which can hold the maximum number of arguments used by the property.

2017-09-15dtoc: Put phandle args in an arraySimon Glass
We want to support more than one phandle argument. It makes sense to use an array for this rather than discrete struct members. Adjust the code to support this. Rename the member to 'arg' instead of 'id'. Signed-off-by: Simon Glass <sjg@chromium.org> Tested-by: Kever Yang <kever.yang@rock-chips.com>
2017-09-15dtoc: Put each phandle on a separate lineSimon Glass
When writing values from properties which contain phandles, dtoc currently writes 8 phandles per line. Change this to write one phandle per line. This helps reduce line length, since phandles are generally longer and may have arguments. Signed-off-by: Simon Glass <sjg@chromium.org> Tested-by: Kever Yang <kever.yang@rock-chips.com>
2017-09-15dtoc: Rename the phandle structSimon Glass
Rather than naming the phandle struct according to the number of cells it uses (e.g. struct phandle_2_cell) name it according to the number of arguments it has (e.g. struct phandle_1_arg).

2017-09-15dtoc: Handle 'reg' properties with unusual sizesSimon Glass

2017-09-15dtoc: Add support for 32 or 64-bit addressesSimon Glass
When using 32-bit addresses dtoc works correctly. For 64-bit addresses it does not since it ignores the #address-cells and #size-cells properties. Update the tool to use fdt64_t as the element type for reg properties when either the address or size is larger than one cell. Use the correct value so that C code can obtain the information from the device tree easily. Alos create a new type, fdt_val_t, which is defined to either fdt32_t or fdt64_t depending on the word size of the machine. This type corresponds to fdt_addr_t and fdt_size_t. Unfortunately we cannot just use those types since they are defined to phys_addr_t and phys_size_t which use 'unsigned long' in the 32-bit case, rather than 'unsigned int'. Add tests for the four combinations of address and size values (32/32, 64/64, 32/64, 64/32). Also update existing uses for rk3399 and rk3368 which now need to use the new fdt_val_t type.
