Subject: physmap: make map_info customizable
From: Atsushi Nemoto <anemo@xxxxxxxxxxxxx>
Add a hook to physmap_flash_data for map_info initialization. This makes
platform code can customize map operations.
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.
