Those interested in SMP booting on ARM may be interested in http://www.linux-arm.org/LinuxBootLoader/SMPBoot
On ARM supplied development boards we rely on the pre-installed ARM Boot Monitor to provide the necessary setup to allow U-Boot to run uni-core. I am about to look at a patch for the ARM Fast Model A9 multicore in order to boot it without an ARM Boot Monitor. I'll cc this list once it is added to git://linux-arm.org/u-boot-armdev Apologies for the disclaimer - our sys admins seemd to have decided to close my open-source account.......
