[PATCH] S3C64XX: Basic A&W6410 board support patch V2
A&W6410 board uses Samsung S3C6410 SoC and it is registered with 2183. Framebuffer and ethernet devices are supported currently. Unnecessary header file is removed. Fix to use __raw_writel() and __raw_readl() for accessing mapped address. Thank you for your comments.
