How to include sysmap in 2.6 kernel image

[gshan]

Hey Guys,

Recently, I'm working on xmon. The xmon needs sysmap for symbol lookup, 
however I don't know how to include sysmap to uImage. I looked the 
kernel source code for a while and found the kernel image need contain 
struct bi_record *rec. Everybody knows how to include this?

arch/ppc/kernel/setup.c::parse_bootinfo()

void parse_bootinfo(struct bi_record *rec)
{
      if (rec == NULL || rec->tag != BI_FIRST)
              return;
      while (rec->tag != BI_LAST) {
              ulong *data = rec->data;

              printk(KERN_INFO "%s:*********** 0x%08lx\n", 
__FUNCTION__, rec->tag);

              switch (rec->tag) {
              case BI_CMD_LINE:
                      strlcpy(cmd_line, (void *)data, sizeof(cmd_line));
                      break;
              case BI_SYSMAP:
                      sysmap = (char *)((data[0] >= (KERNELBASE)) ? 
data[0] :
                                        (data[0]+KERNELBASE));
                      sysmap_size = data[1];
                      break;
#ifdef CONFIG_BLK_DEV_INITRD
              case BI_INITRD:
                      initrd_start = data[0] + KERNELBASE;
                      initrd_end = data[0] + data[1] + KERNELBASE;
                      break;
#endif /* CONFIG_BLK_DEV_INITRD */
#ifdef CONFIG_PPC_MULTIPLATFORM
              case BI_MACHTYPE:
                      _machine = data[0];
                      break;
#endif
              case BI_MEMSIZE:
                      boot_mem_size = data[0];
                      break;
              }
              rec = (struct bi_record *)((ulong)rec + rec->size);
      }
}


Thanks,
Gavin
