System ID and creation timestamp (sysid)

Yes, the u-boot code supports this. Here&#39;s a snip of code from cpu/nios2/sysid.c (code

is available at: http://www.psyent.com/download (http://www.psyent.com/download) )

void display_sysid (void)
{
        struct nios_sysid_t *sysid = (struct nios_sysid_t *)CFG_NIOS_SYSID_BASE;
        struct tm t;
        char asc;
        time_t stamp;
        stamp = readl (&sysid->timestamp);
        localtime_r (&stamp, &t);
        asctime_r (&t, asc);
        printf ("SYSID : %08x, %s", readl (&sysid->id), asc);
}

I believe the hal has support for asctime_r and localtime_r ... if not, you can just

hoist the code from the u-boot sources.
