to add here, I ran 70 different randconfigs, all seeds are available on
pastebin (took RMK's 4430sdp seed as a starting point):

am33xx-only.config	http://pastebin.com/nVA3xSwb
am43xx-only.config	http://pastebin.com/RbUdKuUh
dra7xx-only.config	http://pastebin.com/ribnaSzS
omap2-only.config	http://pastebin.com/QPUG0wqe
omap3-only.config	http://pastebin.com/B8ctX8yM
omap4-only.config	http://pastebin.com/3D8NAExm
omap5-only.config	http://pastebin.com/3mtQN38Z

Had a total of 16 failing builds, all .configs were also published on
pastebin:

config-am33xx-only.config-1	http://pastebin.com/5xhXZpev
config-am33xx-only.config-2	http://pastebin.com/NsrruJcQ
config-am33xx-only.config-3	http://pastebin.com/CGbB3qb8
config-am33xx-only.config-4	http://pastebin.com/86cu0uZ1
config-am43xx-only.config-1	http://pastebin.com/MCBCAd4X
config-am43xx-only.config-3	http://pastebin.com/hVpCgwSn
config-am43xx-only.config-4	http://pastebin.com/8SXAKHed
config-am43xx-only.config-6	http://pastebin.com/59riPMfw
config-am43xx-only.config-8	http://pastebin.com/03bt2VEZ
config-am43xx-only.config-9	http://pastebin.com/tePGwtWA
config-am43xx-only.config-10	http://pastebin.com/nrtXPqrF
config-omap2-only.config-2	http://pastebin.com/AKyvMqQU
config-omap2-only.config-4	http://paste.debian.net/75329
config-omap2-only.config-5	http://paste.debian.net/75330/
config-omap2-only.config-7	http://paste.debian.net/75332/
config-omap2-only.config-10	http://paste.debian.net/75333/

Failing configs all build fine on v3.13-rc7 except for
config-omap2-only.config-10, which fails due to a broken staging driver.
