12 | # There are three cases to care about: |
13 | # 1. Building kernel with CONFIG_FIRMWARE_IN_KERNEL=y -- $(fw-shipped-y) should | |
14 | # include the firmware files to include, according to .config | |
15 | # 2. 'make modules_install', which will install firmware for modules, and | |
16 | # _also_ for the in-kernel drivers when CONFIG_FIRMWARE_IN_KERNEL=n | |
17 | # 3. 'make firmware_install', which installs all firmware, unconditionally. | |

19 | # For the former two cases we want $(fw-shipped-y) and $(fw-shipped-m) to be |
20 | # accurate. In the latter case it doesn't matter -- it'll use $(fw-shipped-all). | |
21 | # But be aware that the config file might not be included at all. | |
