Could you explain the purpose of this change on S5P64x0?

This is actually quite a poor platform choice. As of today, the kernel
is stuck with supporting just SMDK6440/6450 boards, which are proprietary
development boards and it doesn't look like any further boards will show
up in future. Kukjin has actually proposed removing support for this
platform at all and I consider this reasonable.

Kukjin, should we proceed with removal?

Best regards,
Tomasz
