Right, with this applied, things are better:

1. omap3430ldp allnoconfig is the first build without warnings, congrats.
2. omap4430sdp allnoconfig has a bunch of new section mismatch warnings,
   a couple of compiler warnings, and builds:

WARNING: arch/arm/mach-omap2/built-in.o(.text+0x183c): Section mismatch in reference from the function omap2_init_processor_devices() to the function .init.text:_init_omap_device()
The function omap2_init_processor_devices() references
the function __init _init_omap_device().
This is often because omap2_init_processor_devices lacks a __init 
annotation or the annotation of _init_omap_device is wrong.

arch/arm/mach-omap2/io.c:51: warning: 'omap24xx_io_desc' defined but not used
arch/arm/mach-omap2/omap-wakeupgen.c:181: warning: 'wakeupgen_irqmask_all' defined but not used

3. omap4430sdp randconfig built with these omap specific warnings (exluding
   ones already mentioned):

arch/arm/mach-omap2/board-n8x0.c:39: warning: 'slot1_cover_open' defined but not used
arch/arm/mach-omap2/board-n8x0.c:40: warning: 'slot2_cover_open' defined but not used
arch/arm/mach-omap2/board-n8x0.c:41: warning: 'mmc_device' defined but not used

and, of course, this is with these configs building OMAP2..OMAP4 because of
the config.
