[PATCH v2] ARM: S3C64XX: add support for mach-mini6410

[augulis.darius@gmail.com (Darius Augulis)]

Kukjin,

please replace old patch in my previously sent series with this new one.
Other I think should be OK. Could you please add this series to your 
tree? I'm afraid it's too late to have it in 2.3.37 even thought I sent 
them early enough.

Thanks,
Darius
