/*
Add a hook to physmap_flash_data for map_info initialization. This makes platform code can customize map operations. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> --- 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(-)
