12 * Modifications:
13 * 24-Aug-2004 BJD Start of generic S3C24XX support
14 * 18-Oct-2004 BJD Moved board struct into this file
15 * 04-Jan-2005 BJD New uart initialisation
16 * 10-Jan-2005 BJD Moved generic init here, specific to cpu headers
17 * 14-Jan-2005 BJD Added s3c24xx_init_clocks() call
18 * 10-Mar-2005 LCVR Changed S3C2410_{VA,SZ} to S3C24XX_{VA,SZ} & IODESC_ENT
19 * 14-Mar-2005 BJD Updated for __iomem
