I test your updated branch, and find there is some errors:

I don't know what's there in vexpress_defconfig. How everybody else is using this is, merge tixy integration branch with my branch (It may already have my branch).
Then do merge of linaro base config, vexpress.conf, ubuntu or android.conf. All above from linaro/configs/*

This can happen due to some mismatched dependencies. You just need to check dependencies. Even i get lot of errors when i merge configs mentioned earlier.
Any suggestion for this?
Also when launch the MP system, how could I know there already two cluster are running? For I only see one cpu by checking cpuinfo. The system I am running actually is A15x1-A7x1 over fastmodel...
Check cpu domain information. pass sched_debug in cmdline params and check boot prints.
