V4:
1. Adjust SPL patch order
2. seperate the patch of "arm1176: Fixed No relocation.", It is a common issue for arm
platform. I sent it for other thread.
V3:
1. Replace ELFIN with S3C64XX for all the variable of cpu.h.
2. Change __S3C6400_H__ into __CPU__H__.
3. Use C language to implement memory initialization.
4. Use C language to re-write reset function.
5. Delete u-boot-nand.lds.
V2:
1. Modify the type of return for s3c64xx_get_base_nand
2. Add patch 0014 to support s3c6410 board
3. Adjust patch for mix content.
V1:
This serial patch intent to:
1. Switch all I/O to use readl/writel function
2. Change nand_spl to use SPL framework
3. S3C64XX serial includes s3c6400 and s3c6410,
Here seprate cpu and board file to support to board's of s3c6410.
I test this patch on my s3c6410 development board. the log as following:
U-Boot 2012.07-rc3-00016-g351ea73 (Jul 28 2012 - 16:55:32) for DMATEK6410

S3C64XX: Switch to use readl/writel to operate nand flash
S3C64XX: Use readl/writel to operate uart
S3C64XX: add pwm for s3c64xx support
S3C64XX: reference s5p cpu time system for s3c64xx timer
S3C64xx: mov cpu_init.S to the board directory
S3C6400: Adopt SPL framwork to support spl for nand flash
S3C6400: Delete nand_spl for S3C6400
S3C64XX: Change SROM init to use read/write operation
S3C64XX: Switch to use read/writel to operation clock system
S3c64xx: clear GPIO, Interrupt, Watchdog variable.
S3C6400: clear memory init variable
S3C64XX: Move s3c6400.h to cpu.h to support s3c6410 board
S3C6400: Remove the unused variable for S3C6400

Change for V4:
- None.
Change for V3:
- Replace the magic numbers with variable name.
Change for V2:
- Change the type of the return value from unsinged int
to unsinged long for s3c64xx_get_base_uart function.
- Delete const for the local variable.

Change for V4:
- None.
Change for v3:
- None.
Change for V2:
- Change the type of the return value from unsinged int
to unsinged long for s3c64xx_get_base_uart function.
- Delete const for the local variable.

To: u-boot
From: Zhong Hongbo <bocui107@gmail.com>
The old spl use nand_spl directory file to support
nand flash boot. We will adopt the new SPL framework
to implement it.

Change for V4:
- Adjust the patch's order.
Change for V3:
- Delete u-boot-nand.lds.
Change for V2:
- None.
