2018-01-18util/blobtool: rename to bincfgDenis 'GNUtoo' Carikli
The name blobtool is confusing as 'blob' is also used to describe nonfree software in binary form. Since this utility deals with binary configurations it makes more sense to call it bincfg.

2017-04-24util/blobtool: clean up blobtool.l a bitMartin Roth
- Rewrite STRING and COMMENT expressions to remove need for CHARS. - Clean up regular expressions - get rid of unnecessary expressions. - Remove extra newline from the end of the file. - Clean up stripquotes() function -- Remove unnecessary backslashes in '\"' -- Check malloc for failure -- Remove unnecessary assignment of 0 to the end of the new string, snprintf will take care of it. - Update blobtool.lex.c_shipped to the new version.

2017-02-04util/blobtool: Add new tool for compiling/decompiling data blobsDamien Zammit
Given a specification of bitfields defined e.g. as follows: specfile: { "field1" : 8, "field2" : 4, "field3" : 4 } and a set of values for setting defaults: setterfile: { "field1" = 0xff, "field2" = 0xf, "field3" = 0xf } You can generate a binary packed blob as follows: ./blobtool specfile setterfile binaryoutput binaryoutput: ff ff The reverse is also possible, i.e. you can regenerate the setter: ./blobtool -d specfile binaryoutput setterorig setterorig: # AUTOGENERATED SETTER BY BLOBTOOL { "field1" = 0xff, "field2" = 0xf, "field3" = 0xf } This tool comes with spec/set files for X200 flash descriptor and ICH9M GbE region, and can be extended or used to decompile other data blobs with known specs.
