util/blobtool: Add new tool for compiling/decompiling data blobs
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.
