| 30 | # Rules for patching source that is downloaded and unpacked or pulled from | |
| 31 | # a source repository. Patches should be named | |
| 32 | # patches/{patch-file-name}.patch{version} where {patch-file-name} is a | |
| 33 | # meaningful name for the patch contents and {version} corresponds to the | |
| 34 | # COMPONENT_NAME{version} of the source to be patched. Typically, version | |
| 35 | # would be something like "_1", "_2", ... After all {version} patches have | |
| 36 | # been applied, a final set of patches without a {version} suffix may be | |
| 37 | # applied. | |
| 38 | # | |
| 39 | # PATCH_DIR can be overridden to move patches to a different location | |
| 40 | # PATCH_PATTERN can be overridden to adjust the patch naming scheme that the | |
| 41 | # build recognizes. | |
| e1ec34 | 42 | # ADDITIONAL_PATCHES can be defined in the component Makefile to include |
| e28f4f | 43 | # additional patches. |
