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.
