CFI Flash - "NOR chip too large" error on uCLinux

Hi,

The message "NOR chip too large to fit in mapping. Attempting to cope..." is produced in the function 'genprobe_ident_chips' like

static struct cfi_private *genprobe_ident_chips(struct map_info *map, struct chip_probe *cp)
{
    struct cfi_private cfi;
    struct cfi_private *retcfi;
    unsigned long *chip_map;
    int i, j, mapsize;
    int max_chips;
<skip>...
    /*
     * Allocate memory for bitmap of valid chips.
     * Align bitmap storage size to full byte.
     */
    max_chips = map->size >> cfi.chipshift;
    if (!max_chips) {
        printk(KERN_WARNING "NOR chip too large to fit in mapping. Attempting to cope...\n");
        max_chips = 1;
    }
    mapsize = sizeof(long) * DIV_ROUND_UP(max_chips, BITS_PER_LONG);
    chip_map = kzalloc(mapsize, GFP_KERNEL);

So you must enlarge the 'map->size', but I don't know where this value is set.
