D-Cache on a NOR flash device

[Davide CASCONE]

How can I enable the D-CACHE on a NOR flash device? I have add in the flash probe function (omapflash_probe() in the file drivers/mtd/maps/omap_nor.c) the following instructions:

struct omapflash_info {
	struct mtd_partition	*parts;
	struct mtd_info		*mtd;
	struct map_info		map;
};

...

struct omapflash_info *info;

...

static int __devinit omapflash_probe(struct platform_device *pdev)
{
...
	info->map.cached = ioremap_cached(res->starts, size);
	if(!info->map.cached ){
		printk(KERN_WARNING "Failed to ioremap cached %s\n", info->map.name);
	}
...
}

Is it enough?

Thanks in advance,
Davide
