[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.
