dtc: ensure #line directives don't consume data from the next line

2013-06-13T21:12:15Z

Previously, the #line parsing regex ended with ({WS}+[0-9]+)?. The {WS} could match line-break characters. If the #line directive did not contain the optional flags field at the end, this could cause any integer data on the next line to be consumed as part of the #line directive parsing. This could cause syntax errors (i.e. #line parsing consuming the leading 0 from a hex literal 0x1234, leaving x1234 to be parsed as cell data, which is a syntax error), or invalid compilation results (i.e. simply consuming literal 1234 as part of the #line processing, thus removing it from the cell data). Fix this by replacing {WS} with [ \t] so that it can't match line-breaks. Convert all instances of {WS}, even though the other instances should be irrelevant for any well-formed #line directive. This is done for consistency and ultimate safety.

dtc: Update generated files to output from Bison 2.5

2013-06-13T21:12:14Z

This patch merely updates the generated dtc parser and lexer files to the output generated by Bison 2.5. The previous versions were generated from version 2.4.1. The only reason for this commit is to minimize the diff on the next commit which fixes a bug in the DTC #line directive parsing. Otherwise the Bison changes would be intermingled with the functional changes. Signed-off-by: Grant Likely

dtc: fix for_each_*() to skip first object if deleted

2012-10-17T20:53:04Z

The previous definition of for_each_*() would always include the very first object within the list, irrespective of whether it was marked deleted, since the deleted flag was not checked on the first object, but only on any "next" object. Fix for_each_*() to check the deleted flag in the loop body every iteration to correct this.

dtc: import latest upstream dtc

2012-10-01T16:11:35Z

This updates scripts/dtc to commit 317a5d9 "dtc: zero out new label objects" from git://git.jdl.com/software/dtc.git. This adds features such as: * /bits/ syntax for cell data. * Math expressions within cell data. * The ability to delete properties or nodes. * Support for #line directives in the input file, which allows the use of cpp on *.dts. * -i command-line option (/include/ path) * -W/-E command-line options for error/warning control. * Removal of spew to STDOUT containing the filename being compiled. * Many additions to the libfdt API.
