- Kconfig: Write tmp files into same directory as target files
-
- This removes the need for COREBOOT_BUILD_DIR in Kconfig. Since the
- original files will be replaced with the tmp file, the parent directory
- already needs to be writable.
-
- Before this change, the tmp files would be created in the CWD (src) if
- COREBOOT_BUILD_DIR was not specified.
-
- BUG=b:112267918
- TEST=emerge-grunt coreboot and verified no tmp files were created in the
- src directory.
