Scott's original patch does still have some implementation details I
didn't like. So in the interests of saving time, I've addressed some
of those, added a testcase, and and now resubmitting my revised
version of Scott's patch.
dtc: Add support for binary includes.
A property's data can be populated with a file's contents
as follows:
node {
prop = /incbin/("path/to/data");
};
A subset of a file can be included by passing start and size parameters.
For example, to include bytes 8 through 23:
node {
prop = /incbin/("path/to/data", 8, 16);
};
As with /include/, non-absolute paths are looked for in the directory
of the source file that includes them.
Implementation revised, and a testcase added by David Gibson
