This makes platform code can customize map operations. Signed-off-by: Atsushi Nemoto --- Background: I wrote this patch to support RBTX4939 board, which requires custom map->{read,write,copy_from} function. I think extending the physmap driver is better than adding a new map driver. drivers/mtd/maps/physmap.c | 5 ++++- include/linux/mtd/physmap.h | 1 + 2 files changed, 5 insertions(+), 1 deletions(-) diff --git a/drivers/mtd/maps/physmap.c b/drivers/mtd/maps/physmap.c index dfbf3f2..7ca048d 100644 --- a/drivers/mtd/maps/physmap.c +++ b/drivers/mtd/maps/physmap.c @@ -128,7 +128,10 @@ static int physmap_flash_probe(struct platform_device *dev) goto err_out; } - simple_map_init(&info->map[i]); + if (physmap_data->map_init) + (*physmap_data->map_init)(&info->map[i]); + else + simple_map_init(&info->map[i]); probe_type = rom_probe_types; for (; info->mtd[i] == NULL && *probe_type != NULL; probe_type++) diff --git a/include/linux/mtd/physmap.h b/include/linux/mtd/physmap.h index c8e63a5..bf51a63 100644 --- a/include/linux/mtd/physmap.h +++ b/include/linux/mtd/physmap.h @@ -25,6 +25,7 @@ struct physmap_flash_data { void (*set_vpp)(struct map_info *, int); unsigned int nr_parts; struct mtd_partition *parts; + void (*map_init)(struct map_info *map); }; /* -- 1.5.6.3 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
