Evgeny Voevodin 078758d074 hw/arm_boot.c: Make SMP boards specify address to poll in bootup loop
The secondary CPU bootloader in arm_boot.c holds secondary CPUs in a
pen until the primary CPU releases them. Make boards specify the
address to be polled to determine whether to leave the pen (it was
previously hardcoded to 0x10000030, which is a Versatile Express/
Realview specific system register address).
