2018-09-29core: Add dev_{disable,enable}_by_pathMario Six
We cannot use device structures to disable devices, since getting them with the API functions would bind and activate the device, which would fail if the underlying device does not exist. Reviewed-by: Simon Glass <sjg@chromium.org>
2018-09-29test: Add tests for DT-manipulation functionsMario Six
Add tests for the ofnode_set_enabled, ofnode_write_string, and ofnode_write_property functions. Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Mario Six <mario.six@gdsys.cc>
2018-09-29core: Add functions to set properties in live-treeMario Six
Implement a set of functions to manipulate properties in a live device tree: * ofnode_write_prop() to set generic properties of a node * ofnode_write_string() to set string properties of a node * ofnode_set_enabled() to either enable or disable a node Signed-off-by: Mario Six <mario.six@gdsys.cc> Reviewed-by: Simon Glass <sjg@chromium.org>
2018-09-29binman: Allow writing a map file when something goes wrongSimon Glass
When we get a problem like overlapping regions it is sometimes hard to figure what what is going on. At present we don't write the map file in this case. However the file does provide useful information. Catch any packing errors and write a map file (if enabled with -m) to aid debugging. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-09-29binman: Support ELF files for U-Boot and SPLSimon Glass
For sandbox we want to put ELF files in the image since that is what we need to execute. Add support for this. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-09-29binman: Correct fmap output on x86Simon Glass
Normally x86 platforms use the end-at-4gb option. This currently produces an FMAP with positions which have a large offset. The use of end-at-4gb is a useful convenience within binman, but we don't really want to export a map with these offsets. Fix this by subtracting the 'skip at start' parameter. Also put the code which convers names to fmap format, for clarity. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-09-29binman: Record the parent section of each sectionSimon Glass
At present sections have no record of their parent so it is not possible to traverse up the tree to the root and figure out the position of a section within the image. Change the constructor to record this information. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-09-29binman: Support x86 microcode in TPLSimon Glass
When TPL is used on x86 we may want to program the microcode (at least for the first CPU) early in boot. Add support for this by refactoring the existing code to be more generic. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-09-29binman: Support hashing entriesSimon Glass
Sometimesi it us useful to be able to verify the content of entries with a hash. Add an easy way to do this in binman. The hash information can be retrieved from the device tree at run time. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-09-29binman: Mention section attributes in docsSimon Glass
Images and sections have the same attributes, since an image is mostly just a top-level section. Update the docs to explain this. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-09-29binman: Support expanding entriesSimon Glass
It is useful to have entries which can grow automatically to fill available space. Add support for this. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-09-29binman: Support adding filesSimon Glass
In some cases it is useful to add a group of files to the image and be able to access them at run-time. Of course it is possible to generate the binman config file with a set of blobs each with a filename. But for convenience, add an entry type which can do this. Add required support (for adding nodes and string properties) into the state module. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-09-29binman: Allow zero-size sectionsSimon Glass
At present if there is only a zero-size entry in a section this is reported as an error, e.g.: Offset 0x0 (0) is outside the section starting at 0x0 (0) Adjust the logic in CheckEntries() to avoid this. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-09-29binman: Support compressed entriesSimon Glass
Add support for compressing blob entries. This can help reduce image sizes for many types of data. It requires that the firmware be able to decompress the data at run-time. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-09-28patman: Detect missing tools and report themSimon Glass
When tools are needed but not present, at present we just get an error which can be confusing for the user. Try to be helpful by reporting the tool as missing and suggesting a possible remedy. Also update the Run() method to support this. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-09-28binman: Support updating all device tree filesSimon Glass
Binman currently supports updating the main device tree with things like the position of each entry. Extend this support to SPL and TPL as well, since they may need (a subset of) this information. Also adjust DTB output files to have a .out extension since this seems clearer than having a .dtb extension with 'out' in the name somwhere. Also add a few missing comments and update the DT setup code to use ReadFile and WriteFile(). Signed-off-by: Simon Glass <sjg@chromium.org>
2018-09-28binman: Allow control of whether a fake DT is usedSimon Glass
We use a fake device tree in tests most of the time since tests don't normally care about the actual data. For example, for U-Boot proper we use U_BOOT_DTB_DATA which is just a four-character string. This makes testing the image output against an expected value very easy. However in some cases, such as when the test wants to check that the DT output containing particular nodes, we do actually need the real DT. Add support for this, along with a command-line option to select 'test mode'. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-09-28binman: Obtain the list of device trees from the configSimon Glass
We always have a device tree for U-Boot proper. But we may also have one for SPL and TPL. Add a new Entry method to find out what DTs an entry has, and use that list when updating DTs. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-09-28binman: Centralise device-tree updates within binmanSimon Glass
At present we have a few calls to device-tree functions in binman and plan to add more as we add new entry types which need to report their results. It makes sense to put this code in a central place so that we can make sure all device trees are updated. At present we only have U-Boot proper, but plan to add SPL and TPL too.

2018-09-28binman: Move state logic into the state moduleSimon Glass
Rather than reaching into this module from control, move the code that needs this info into state. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-09-28binman: Move state information into a new moduleSimon Glass
At present the control module has state information in it, since it is the primary user of this. But it is a bit odd to have entries and other modules importing control to obtain this information. It seems better to have a dedicated state module, which control can use as well. Create a new module using code from control and update other modules to use it. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-09-28binman: Add an entry method for getting the default filenameSimon Glass
Various entry implementations provide a way to obtain the default filename for an entry. But at present there is no base-class implementation for this function. Add one so that the API is defined. 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>
2018-09-28binman: Support building a selection of imagesSimon Glass
Sometimes it is useful to build only a subset of the images provided by the binman configuration. Add a -i option for this. It can be given multiple times to build several images. If the option is not given, all images are built. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-09-28binman: Tidy up the vblock entrySimon Glass
At present if there are two vblock entries an image their contents are written to the same file in the output directory. This prevents checking the contents of each separately. Fix this by adding part of the entry path to the filename, and add some missing comments. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-09-28binman: Add x86 support for starting TPLSimon Glass
Sometimes we want to include TPL for x86 platforms, such as when we want to select between different SPL images (e.g. for Chrome OS verified boot). Add support for this. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-09-28binman: Generate an error when text is not providedSimon Glass

2018-09-26sandbox: Fix set_working_fdt_addr usersAlexander Graf
When running sandbox with the new pointer sanitization we just recently introduced, we're running into a case with FIT images where we end up interpreting pointers as addresses. What happened is that most callers of set_working_fdt_addr() simply convert pointers into addresses without taking into account that they might be 2 separate address spaces. Fix the callers up to map their pointers into addresses. This makes sandbox tests pass for me again. Signed-off-by: Alexander Graf <agraf@suse.de>

2018-09-26fpga: zynqmp: Modify PL bitstream loading sequenceSiva Durga Prasad Paladugu
This patch modifies PL bitstream loading sequence as per latest Xilfpga which supports all variants of bitstream images generated from vivado and from bootgen. With this new change in Xilfpga, uboot doesn't need to validate and swap bitstream as it will be taken care inside Xilfpga. ZynqMP PL driver now checks for supporting PMUFW version before skipping the validation and swap sequence as there can be old PMUFW which doesn't supports this feature. In this case, driver uses old way of PL bitstream loading sequence. Signed-off-by: Siva Durga Prasad Paladugu <siva.durga.paladugu@xilinx.com> Signed-off-by: Michal Simek <michal.simek@xilinx.com>

2018-09-25Makefile: Use -fno-strict-aliasing globallyBin Meng
The -fstrict-aliasing option is implicitly enabled at levels -O2, -O3, -Os by GCC. This option allows the compiler to assume the strictest aliasing rules applicable to the language being compiled. For example, the practice of reading from a different union member than the one most recently written to (called "type-punning") is common. In this case, "type-punning" only works if the memory is accessed through the union type, but might not work by taking the address, casting the resulting pointer and dereferencing the result, which is an undefined behavior per the "strict aliasing rules". GCC's -Wstrict-aliasing (included in -Wall) option does not catch all cases, but does attempt to catch the more common pitfalls. So there are cases that GCC does not report but the codes are violating the "strict aliasing rules". Given lots of codes that may be written to rely on "type-punning", and Linux kernel disables it by -fno-strict-aliasing globally, since U-Boot currently does this on nds32/riscv/x86 builds only, extend this for all architecture builds.
