The MINI2416 board is based on a Samsung's S3C2416 SoC and has 64MB DDR2 SDRAM,
256MB NAND Flash, a LAN9220 Ethernet Controller and a WM8731 Audio CODEC.
This U-Boot port was implemented and tested on a unit bought to Boardcon
(http://www.armdesigner.com/) but there are some other chinese providers
that can supply it with a selectable NAND chip from 128MB to 1GB.

Changes for v2:
- Coding style cleanup
- Use of Use of clrbits_le32(), setbits_le32() and clrsetbits_le32()
- Use of register bit macros instead of magic numbers
- Use of serial and rtc drivers implemented for s3c24x0
