And the grand cure for that sort of issue is FDT - we by now have built
big deserts of code just registering platform devices like this.. See
John Crispin's Lantiq work or David's Cavium code for FDT examples.

Don't use __init in declarations. It doesn't make any difference to the
compiler but it may cause build errors if <linux/init.h> has not been
included before which this file doesn't.

I suggest to make bcm63xx_flash_register an arch_initcall. It already is
being called indirectly from an bcm63xx_flash_register() so this would
allow making the function static, get rid of bcm63xx_dev_flash.h which
only exists to silence checkpatch warnings and make board_register_devices
a little cleaner.

PS: Don't forget about FDT :-) Eventually, not necessarily now.
