binman: Add command-line support for replacing entries

2019-07-29T15:38:06Z

Add a 'replace' command to binman to permit entries to be replaced, either individually or all at once (using a filter). Signed-off-by: Simon Glass

binman: Correct the error message for invalid path

2019-07-29T15:38:06Z

At present this message references -o for output file. But binman uses -f now. Fix it. Signed-off-by: Simon Glass

binman: Clean up all output directories in tests

2019-07-29T15:38:06Z

At present some tests leave behind output directories. This happens because some tests call binman, which sets up an output directory, then call it again, which sets up another output directory and leaves the original one behind. Fix this by using a separate temporary directory when binman is called twice, or by manually removing the output directory. Signed-off-by: Simon Glass

binman: Add a test function to clean up the output dir

2019-07-29T15:38:06Z

Put tearDown()'s logic into a new _CleanupOutputDir() function so that it can be called from elsewhere. Signed-off-by: Simon Glass

binman: Support replacing data in a cbfs

2019-07-29T15:38:06Z

At present binman cannot replace data within a CBFS since it does not allow rewriting of the files in that CBFS. Implement this by using the new WriteData() method to handle the case. Add a header to compressed data so that the amount of compressed data can be determined without reference to the size of the containing entry. This allows the entry to be larger that the contents, without causing errors in decompression. This is necessary to cope with a compressed device tree being updated in such a way that it shrinks after the entry size is already set (an obscure case). It is not used with CBFS since it has its own metadata for this. Increase the number of passes allowed to resolve the position of entries, to handle this case. Add a test for this new logic.

binman: Place Intel descriptor at image start

2019-07-29T15:38:06Z

The Intel descriptor must always appear at the start of an (x86) image, so it is supposed to position itself there always. However there is no explicit test for this. Add one and fix a bug introduced by the recent change to adjust Entry to read the node in a separate call. Signed-off-by: Simon Glass

binman: Support shrinking a entry after packing

2019-07-29T15:38:06Z

Sometimes an entry may shrink after it has already been packed. In that case we must repack the items. Of course it is always possible to just leave the entry at its original size and waste space at the end. This is what binman does by default, since there is the possibility of the entry changing size every time binman calculates its contents, thus causing a loop. Signed-off-by: Simon Glass

binman: Update the _testing entry to support shrinkage

2019-07-29T15:38:06Z

Sometimes entries shrink after packing. As a start towards supporting this, update the _testing entry to handle the test case. Signed-off-by: Simon Glass

binman: Allow updating entries that change size

2019-07-29T15:38:06Z

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.

binman: Add more tests for image header position

2019-07-29T15:38:06Z

The positioning does not currently work correctly if at the end of an image with no fixed size. Also if the header is in the middle of an image it can cause a gap in the image since the header position is normally at the image end, so entries after it are placed after the end of the image. Fix these problems and add more tests to cover these cases. Signed-off-by: Simon Glass
