mtd: maps: Prepare merging of physmap and physmap_of

2018-11-05T21:24:20Z

We want to merge the physmap and physmap_of driver, but before we can do that we must prepare things to create physmap.o out of several .c files. Rename physmap.c into physmap-core.c and add a new Makefile rule to create physmap.o (right now it only contains physmap-core.o).

mtd: maps: physmap: Return -ENOMEM directly when info allocation fails

2018-11-05T21:24:10Z

mtd: maps: physmap: Use platform_get_resource() to retrieve iomem resources

2018-11-05T21:23:43Z

Stop manipulating the dev->resource array directly and use the platform_get_resource() helper instead. While at it, fix the loop check so that we never overflow the info->maps and info->mtds array even if the number of resources attached to the platform dev is higher than MAX_RESOURCES.
