Name:kdb_md - This function implements the 'md', 'md1', 'md2', 'md4',* 'md8' 'mdr' and 'mds' commands.* md|mds [<addr arg> [<line count> [<radix>]]]* mdWcN [<addr arg> [<line count> [<radix>]]]* where W = is the width (1, 2, 4 or 8) and N is the count.* for eg

Proto:static void kdb_md_line(const char *fmtstr, unsigned long addr, int symbolic, int nosect, int bytesperword, int num, int repeat, int phys)
