binman: Add 'min-size' entry property

2023-01-26T17:47:45Z

This property sets the minimum size of an entry, including padding but not alignment. It can be used to reserve space for growth of an entry, or to enforce a minimum offset for later entries in the section. Signed-off-by: Samuel Holland Reviewed-by: Simon Glass

binman: Support positioning an entry by and ELF symbol

2023-01-18T21:55:41Z

In some cases it is useful to position an entry over the top of a symbol in an ELF file. For example, if the symbol holds a version string then it allows the string to be accessed from the fdtmap. Add support for this. Suggested-by: Pali Rohár Suggested-by: Keith Short Signed-off-by: Simon Glass

binman: Provide general support for updating ELF symbols

2023-01-18T21:55:41Z

The current support for updating variables in a binary is hard-coded to work with U-Boot: - It assumes the image starts at __image_copy_start - It uses the existing U-Boot-specific entry types It is useful for other projects to use these feature. Add properties to enable writing symbols for any blob, a way of specifying the base symbol and a way of providing the ELF filename to allow symbol lookup to take place. With this it is possible to update a Zephyr image, such as zephyr.bin after it has been built. Signed-off-by: Simon Glass

binman: Support overlapping entries

2023-01-18T21:55:41Z

In some cases it is useful to have an entry overlap with another in a section, either to update the contents within a blob, or to add an entry to the fdtmap that covers only part of the blob. Add support for this. Signed-off-by: Simon Glass

binman: Add a null entry

2023-01-18T21:55:40Z

It is sometimes useful to define an entry which does not have its own contents but does appear in the image. The contents are set by the section which contains it, even though it appears as an entry in the fdtmap. Add support for this. Signed-off-by: Simon Glass

binman: Clarify use of False when obtaining data

2023-01-18T21:55:40Z

This means that the data is not yet available. Update some comments to make this clearer. Signed-off-by: Simon Glass

binman: Support optional external blobs

2023-01-18T18:50:01Z

Some blobs are actually not necessary for the board to work correctly. Add a property to allow this to be indicated. Missing optional blobs do not cause a build failure. Signed-off-by: Simon Glass

binman: Support new op-tee binary format

2023-01-18T18:50:01Z

OP-TEE has a format with a binary header that can be used instead of the ELF file. With newer versions of OP-TEE this may be required on some platforms. Add support for this in binman. First, add a method to obtain the ELF sections from an entry, then use that in the FIT support. We then end up with the ability to support both types of OP-TEE files, depending on which one is passed in with the entry argument (TEE=xxx in the U-Boot build). Signed-off-by: Simon Glass

binman: Support optional entries

2023-01-18T18:50:01Z

Support entries which can be optional depending on their contents. This allows special entry types which appear in the image only when needed. Signed-off-by: Simon Glass

binman: Support writing symbols into ELF files

2022-10-31T15:02:44Z

In some cases the ELF version of SPL builds may be packaged, rather than a binary .bin file. Add support for this. Signed-off-by: Simon Glass
