Stand alone omap_4430sdp_defconfig also didn't fully boot on the linux-omap "multi-omap4".
The log below shows that the serial platform data isn't configured correctly. 

<6>io scheduler deadline registered
<6>io scheduler cfq registered (default)
<6>Serial: 8250/16550 driver, 4 ports, IRQ sharing enabled
<6>serial8250.0: ttyS0 at MMIO 0x4806a000 (irq = 104) is a ST16654
<6>serial8250.1: ttyS0 at MMIO 0x4806a000 (irq = 105) is a ST16654

Below patch to fix the boot for omap_4430sdp_defconfig. Small typo really.

For multi-omap build, for now I need to disable 
[*] Reset unused clocks during boot

With this OMAP4430 boots with omap3_defconfig :)
