From: Simon Glass <simon.glass@canonical.com> Create include/linux/init.h with stub definitions for kernel initialization macros. U-Boot has its own initialization mechanism. Includes: - Section markers: __init, __exit, __initdata, __devinit, etc. - Initcall levels: core_initcall(), late_initcall(), etc. Update compat.h to include init.h and remove duplicate definitions.
