| # which returns the first overlay patch file for <module> found |
| # in the list of directories <relative dir list...> which are |
| # relative to <patchdir> (itself either absolute or relative to the |
| # current directory). The returned filename is relative to <patchdir>. |
| # For example: |
| # $(call XTENSA_PATCH, binutils, some/dir/path, . ..) |
| # (no commas between directory paths in the list). |
| # |
| # A selected overlay patch must exist ("fsf" means no specific |
| # overlay is selected). So the function emits a Makefile error |
| # if a selected patch file is not found. |
