This introduces small OneNAND loader, fitting into 1kB of space (smallest possible OneNAND RAM size). Some devices equipped with such crappy chips will use this. Signed-off-by: Marek Vasut <marek.vasut@gmail.com> Cc: Albert ARIBAUD <albert.u.boot@aribaud.net> Cc: Kyungmin Park <kyungmin.park@samsung.com> Cc: Scott Wood <scottwood@freescale.com> V2: Introduce spl_onenand_load_image() to load data from OneNAND in SPL V3: Cleanup, align with nand_spl. Skip whole blocks.
