You should get basic things booting with omap2plus_defconfig as long
as you have the machine_id related entry in some mach-omap2/board*.c
file.

Maybe enable DEBUG_LL and EARLY_PRINTK in your .config so you can
verify the machine_id? Note that it requires you to have a suitable
entry in arch/arm/mach-omap2/include/mach/uncompress.h.

You may need to patch in omap_uart_phys/virt/lsr in the related
arch/arm/mach-omap2/include/mach/debug-macro.S if the machine_id
is unknown.
