From: David Brownell <dbrownell@xxxxxxxxxxxxxxxxxxxxx>
Remove more bogus arch_initcall() logic in mach-omap2/board-xyx.c files.
They broke a multi-OMAP build I did, at *RUN TIME* not build time, since
it tried to do the i2c init for every board linked in the kernel.
Remember, init_machine() entries run at arch_initcall() time; that's
where any board-specific init logic should normally go. Any initcalls
in the mach-*/*c files should normally be guarded by tests to make sure
they only run on the relevant hardware (board, cpu). Better yet, get
rid of the initcalls; init_machine() can *explicitly* call the right
version of that code, and pass in board-specific config data; and there
are hooks that can handle cpu-specific stuff too.
A quick glance suggests most of the remaining initcall logic in the
mach-omap2 directory is similarly broken... this patch gets rid of
one frequently-cloned idiom, it should help.
