How all the secondary cores boot in MPCore | |

Hi all, I am investigating the boot process of the ARM11 MPCore on the PB11MPCore (mach-realview) board. Initially, the start_kernel() function is executing on CPU0, it creates kernel_init thead which I assume it is also executing on CPU0 or am I wrong? When kernel_init thread executes, it calls smp_prepare_cpus() in arch/arm/mach-realview/platsmp.c code, where issupposed to start the secondary processors using secondary_startup() (head.S) After this stage, I am completely lost and I couldnt find any related documentation or understand the code :( I really appreciate any goood explanation that clears the stage that comes after kernel_init thread is executing until all processors are up.
