Re: [DNX#2006040142000973] Réf. : Re: [U-Boot-Users] get_ram_size bug and ask [...]

Hello list,

inside the automatic U-Boot patch tracking system a new ticket [DNX#2006040142000973] was created:

Hi Wolfgang,

it seems the code I have was modified. I look in the original cvs version and it seems that the base address isn't restored either.

  [...]
    addr = base;
    save[i] = *addr; <-- save value at base address
    *addr = 0; <--- modify it.

    if ((val = *addr) != 0) {
            <--- error case : restore all values
        [...]
    }

    <-- we forget to restore the value and start to restore value 

@base+1 with save[i-1].

    for (cnt = 1; cnt < maxsize / sizeof (long); cnt <<= 1) {
            addr = base + cnt;      /* pointer arith! */
            val = *addr;
            *addr = save[--i];
            if (val != ~cnt) {
                    size = cnt * sizeof (long);
                    /* Restore the original data before leaving the 

function. */ for (cnt <<= 1; cnt < maxsize / sizeof (long); cnt <<= 1) { addr = base + cnt; *addr = save[--i]; } return (size); } }

regards,

Matthieu
