It does because the firmware lets you use coremask=0x3. If there was only one core, the system should refuse to boot the kernel with that parameter. Note that U-Boot loads the kernel from a separate MSDOS partition. You have to put the multiprocessor kernel there, and check that GENERIC.MP shows up in dmesg. The firmware cannot read the root filesystem because it does not understand the format.
