* 24-Aug-2004 BJD Start of generic S3C24XX support
* 18-Oct-2004 BJD Moved board struct into this file
* 04-Jan-2005 BJD New uart initialisation
* 10-Jan-2005 BJD Moved generic init here, specific to cpu headers
* 14-Jan-2005 BJD Added s3c24xx_init_clocks() call
* 10-Mar-2005 LCVR Changed S3C2410_{VA,SZ} to S3C24XX_{VA,SZ} & IODESC_ENT
* 14-Mar-2005 BJD Updated for __iomem
