[ARM] 4963/1: S3C2410 - add basic machine support for the TCT Hammer
Add the TinCanTools Hammer board to list of supported machines in the arch/arm/mach-s3c2410 directory, as well as a default config entry. the mach-tct_hammer.c file initializes basic i/o, clocks, irqs, as well as the mtd flash layout if enabled in the kernel configuration.
