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.
18
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.
