2019-11-11binman: tegra: Adjust symbol calculation depending on end-at-4gbSimon Glass
A recent change adjusted the symbol calculation to work on x86 but broke it for Tegra. In fact this is because they have different needs. On x86 devices the code is linked to a ROM address and the end-at-4gb property is used for the image. In this case there is no need to add the base address of the image, since the base address is already built into the offset and image-pos properties. On other devices we must add the base address since the offsets start at zero. In addition the base address is currently added to the 'offset' and 'size' values. It should in fact only be added to 'image-pos', since 'offset' is relative to its parent and 'size' is not actually an address. This code should have been adjusted when support for 'image-pos' and 'size' was added, but it was not. To correct these problems: - move the code that handles adding the base address to section.py, which can check the end-at-4gb property and which property (offset/size/image-pos) is being read - add the base address only when needed (only for image-pos and not if the image uses end-at-4gb) - add a note to the documentation - add a separate test to cover x86 behaviour Fixes: 15c981cc (binman: Correct symbol calculation with non-zero image base) Signed-off-by: Simon Glass <sjg@chromium.org> Tested-by: Stephen Warren <swarren@nvidia.com>

2019-07-29binman: Allow updating entries that change sizeSimon Glass
So far we don't allow entries to change size when repacking. But this is not very useful since it is common for entries to change size after an updated binary is built, etc. Add support for this, respecting the original offset/size/alignment constraints of the image layout. For this to work the original image must have been created with the 'allow-repack' property. This does not support entry types with sub-entries such as files and CBFS, but it does support sections.

There are a few more steps in the process now. Update the documentation to reflect this. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-29binman: Add info to allow safely repacking an image laterSimon Glass
At present it is not possible to discover the contraints to repacking an image (e.g. maximum section size) since this information is not preserved from the original image description. Add new 'orig-offset' and 'orig-size' properties to hold this. Add them to the main device tree in the image. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-29binman: Support updating entries in an existing imageSimon Glass
While it is useful and efficient to build images in a single pass from a unified description, it is sometimes desirable to update the image later. Add support for replace an existing file with one of the same size. This avoids needing to repack the file. Support for more advanced updates will come in future patches.

2019-07-24binman: Allow for logging information to be displayedSimon Glass
Binman generally operates silently but in some cases it is useful to see what Binman is actually doing at each step. Enable some logging output with different logging levels selectable via the -v flag. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-24binman: Support listing an imageSimon Glass
Add support for listing the entries in an image. This relies on the image having an FDT map. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-24binman: Allow entries to expand after packingSimon Glass
Add support for detecting entries that change size after they have already been packed, and re-running packing when it happens. This removes the limitation that entry size cannot change after PackEntries() is called. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-24binman: Move compression into the Entry base classSimon Glass
Compression is currently available only with blobs. However we want to report the compression algorithm and uncompressed size for all entries, so that other entry types can support compression. This will help with the forthcoming 'list' feature which lists entries in the image. Move the compression properties into the base class. Also fix up the docs which had the wrong property name.

2019-07-24binman: Convert to use ArgumentParserSimon Glass
This class is the new way to handle arguments in Python. Convert binman over to use it. At the same time, introduce commands so that we can separate out the different parts of binman functionality. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-24binman: Add an image headerSimon Glass
It is useful to be able to quickly locate the FDT map in the image. An easy way to do this is with a pointer at the start or end of the image. Add an 'image header' entry, which places a magic number followed by a pointer to the FDT map. This can be located at the start or end of the image, or at a chosen location. As part of this, update GetSiblingImagePos() to detect missing siblings. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-24binman: Add an FDT mapSimon Glass
An FDT map is an entry which holds a full description of the image entries, in FDT format. It can be discovered using the magic string at its start. Tools can locate and read this entry to find out what entries are in the image and where each entry is located. Signed-off-by: Simon Glass <sjg@chromium.org>

2018-09-27binman: Add a new "skip-at-start" property in Section classJagdish Gediya
Currently binman calculates '_skip_at_start' based on 'end-at-4gb' property and it is used for x86 images. For PowerPC mpc85xx based CPU, CONFIG_SYS_TEXT_BASE is the entry offset of the first entry. It can be 0xeff40000 or 0xfff40000 for nor flash boot, 0x201000 for sd boot etc, so "_skip_at_start" should be set to CONFIG_SYS_TEXT_BASE. 'end-at-4gb' property is not applicable where CONFIG_SYS_TEXT_BASE + Image size != 4gb. Add new property 'skip-at-start' in Section class so that '_skip_at_start' can be calculated either based on 'end-at-4gb' or based on "skip-at-start". Add a test case to check that 'skip-at-start' and 'end-at-4gb' property can't be used together.

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>
2018-08-01binman: Add a new 'image-pos' propertySimon Glass
At present each entry has an offset within its parent section. This is useful for figuring out how entries relate to one another. However it is sometimes necessary to locate an entry within an image, regardless of which sections it is nested inside. Add a new 'image-pos' property to provide this information. Also add some documentation for the -u option binman provides, which updates the device tree with final entry information. Since the image position is a better symbol to use for the position of U-Boot as obtained by SPL, update the SPL symbols to use this instead of offset, which might be incorrect if hierarchical sections are used.

2018-08-01binman: Enhance the map and fdt-update outputSimon Glass
At present the .map file produced for each image does not include the overall image size. This is useful information. Update the code to generate it in the .map file as well as the updated FDT. Also fix a few comments while we are here. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-08-01binman: Rename 'position' to 'offset'Simon Glass
After some thought, I believe there is an unfortunate naming flaw in binman. Entries have a position and size, but now that we support hierarchical sections it is unclear whether a position should be an absolute position within the image, or a relative position within its parent section. At present 'position' actually means the relative position. This indicates a need for an 'image position' for code that wants to find the location of an entry without having to do calculations back through parents to discover this image position. A better name for the current 'position' or 'pos' is 'offset'. It is not always an absolute position, but it is always an offset from its parent offset. It is unfortunate to rename this concept now, 18 months after binman was introduced. However I believe it is the right thing to do. The impact is mostly limited to binman itself and a few changes to in-tree users to binman: tegra sunxi x86 The change makes old binman definitions (e.g. downstream or out-of-tree) incompatible if they use the 'pos = <...>' property. Later work will adjust binman to generate an error when it is used. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-07-09binman: Support updating the device tree with calc'd infoSimon Glass

2018-07-09binman: Add a SetCalculatedProperties() methodSimon Glass
Once binman has packed the image, the position and size of each entry is known. It is then possible for binman to update the device tree with these positions. Since placeholder values have been added, this does not affect the size of the device tree and therefore the packing does not need to be performed again. Add a new SetCalculatedProperties method to handle this. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-07-09binman: Add a ProcessFdt() methodSimon Glass
Some entry types modify the device tree, e.g. to remove microcode or add a property. So far this just modifies their local copy and does not affect a 'shared' device tree. Rather than doing this modification in the ObtainContents() method, and a new ProcessFdt() method which is specifically designed to modify this shared device tree. Move the existing device-tree code over to use this method, reducing ObtainContents() to the goal of just obtaining the contents without any processing, even for device tree.
