binman: Allow for skip_at_start when reading entries

2021-01-30T21:25:41Z

The offset of an entry needs to be adjusted by its skip-at-start value. This is currently missing when reading entry data. Fix it. Signed-off-by: Simon Glass

binman: Support alignment of files

2021-01-30T21:25:41Z

When packing files it is sometimes useful to align the start of each file, e.g. if the flash driver can only access 32-bit-aligned data. Provides a new property to support this. Signed-off-by: Simon Glass

binman: Allow vblock to include devicetree blobs

2021-01-30T21:25:41Z

At present if a devicetree blob is included in a vblock it does not deal with updates. This is because the vblock is created once at the start and does not have a method to update itself later, after all the entry contents are finalised. Fix this by adjusting how the vblock is created. Also simplify Image.ProcessEntryContents() since it effectively duplicates the code in Section.ProcessContents(). Signed-off-by: Simon Glass

binman: Support reading an image with entry args

2021-01-30T21:25:41Z

Normally when an entry is created, any entry arguments it has are required to be provided, so it can actually generate its contents correctly. However when an existing image is read, Entry objects are created for each of the entries in the image. This happens as part of the process of reading the image into binman. In this case we don't need the entry arguments, since we do not intend to regenerate the entries, or at least not unless requested. So there is no sense in reporting an error for missing entry arguments. Add a new property for the Image to handle this case. Update the error reporting to be conditional on this property.

binman: Support finding symbols in sub-sections

2021-01-30T21:25:41Z

At present binman only supports resolving symbols in the same section as the binary that uses it. This is quite limited because we often need to group entries into different sections. Enhance the algorithm to search the entire image for symbols. Signed-off-by: Simon Glass

binman: Support compression of sections

2020-10-29T20:42:59Z

With the previous changes, it is now possible to compress entire sections. Add some tests to check that compression works correctly, including updating the metadata. Also update the documentation. Signed-off-by: Simon Glass

binman: Use the actual contents in CheckSize()

2020-10-29T20:42:59Z

At present this function adds up the total size of entries to work out the size of a section's contents. With compression this is no-longer enough. We may as well bite the bullet and build the section contents instead. Call _BuildSectionData() to get the (possibly compressed) contents and GetPaddedData() to get the same but with padding added. Note that this is inefficient since the section contents is calculated twice. Future work will improve this. This affects testPackOverlapMap() since the error is reported with a different section size now (enough to hold the contents). Update that at the same time. Signed-off-by: Simon Glass

binman: Set section contents in GetData()

2020-10-29T20:42:59Z

Section contents is not set up when ObtainContents() is called, since packing often changes the layout of the contents. Ensure that the contents are correctly recorded by making this function regenerate the section. It is normally only called by the parent section (when packing) or by the top-level image code, when writing out the image. So the performance impact is fairly small. Now that sections have their contents in their 'data' property, update testSkipAtStartSectionPad() to check it. Signed-off-by: Simon Glass

binman: Store the original data before compression

2020-10-29T20:42:59Z

When compressing an entry, the original uncompressed data is overwritten. Store it so it is available if needed. Signed-off-by: Simon Glass

binman: Make section padding consistent with other entries

2020-10-29T20:42:59Z

At present padding of sections is inconsistent with other entry types, in that different pad bytes are used. When a normal entry is padded by its parent, the parent's pad byte is used. But for sections, the section's pad byte is used. Adjust logic to always do this the same way. Note there is still a special case in entry_Section.GetPaddedData() where an image is padded with the pad byte of the top-level section. This is necessary since otherwise there would be no way to set the pad byte of the image, without adding a top-level section to every image. Signed-off-by: Simon Glass
