[PATCH 4/7] onenand init: Pass configuration data from board-*.c files

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Pass configuration data from board-*.c files.

Also remove support for the OMAP_TAG_PARTITION tag.
If the partition info is passed, it should be passed from
cmdline, and probably should be done in a generic way
in the drivers/mtd.
