patman: Adjust 'command' to return strings instead of bytes

2019-11-05T01:15:32Z

At present all the 'command' methods return bytes. Most of the time we actually want strings, so change this. We still need to keep the internal representation as bytes since otherwise unicode strings might break over a read() boundary (e.g. 4KB), causing errors. But we can convert the end result to strings. Add a 'binary' parameter to cover the few cases where bytes are needed. Signed-off-by: Simon Glass

binman: Use the Makefile for u_boot_ucode_ptr

2019-10-15T14:40:02Z

Remove this file from git and instead build it using the Makefile. Update tools.GetInputFilename() to support reading files from an absolute path, so that we can read the Elf test files easily. Also make sure that the temp directory is report in ELF tests as this was commented out. Signed-off-by: Simon Glass

patman: Update command.Run() to handle failure better

2019-10-15T14:40:02Z

At present tools are not expected to fail. If they do an exception is raised but there is no detail about what went wrong. This makes it hard to debug if something does actually go wrong. Fix this by outputting both stderr and stdout on failure. Signed-off-by: Simon Glass

patman: Drop binary parameter

2019-10-15T14:40:02Z

Since cros_subprocess use bytestrings now, this feature not needed. Drop it. Signed-off-by: Simon Glass

patman: Reset the output directory when it is removed

2019-07-29T15:38:06Z

At present outdir remains set ever after the output directory has been removed. Fix this to avoid trying to access it when it is not present. 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: Add a bit of logging in entries when packing

2019-07-29T15:38:05Z

Use the new logging feature to log information about progress with packing. This is useful to see how binman is figuring things out. Also update elf.py to use the same feature. Signed-off-by: Simon Glass

patman: Add a function to write ifwitool

2019-07-24T19:53:46Z

This tool has quite a few arguments and options, so put the functionality in a function so that we call it from one place and hopefully get it right. Signed-off-by: Simon Glass

patman: Add functions to compress and decompress data

2019-07-24T03:27:57Z

Add utility functions to compress and decompress using lz4 and lzma algorithms. In the latter case these use the legacy lzma support favoured by coreboot's CBFS. No tests are provided as these functions will be tested by the CBFS tests in a separate patch. Signed-off-by: Simon Glass

patman: Add a way to set the search path for tools

2019-07-24T03:27:57Z

Sometimes tools can be located by looking in other locations. Add a way to direct the search. Signed-off-by: Simon Glass
