I get freeze if I remove "options SMP" from kernel config.
Also freshly installed OS(VM in ESXi) and freshly installed crochet and src without any patch 
give me un-bootable image....
It seems  current RPI2 code does not work with/without ARM_NEW_PMAP at least r282205.
My host is r281389 (clang 3.6 version) which is same version of ODROID-C1 and RPI version on 
ESXi server.

    Merge pull request #106 from loos-br/master

    Add support to build images for Raspberry Pi 2
