112 * Renesas AND 1 Gigabit. Those chips do not support extended id and
113 * have a strange page/block layout ! The chosen minimum erasesize is
114 * 4 * 2 * 2048 = 16384 Byte, as those chips have an array of 4 page
115 * planes 1 block = 2 pages, but due to plane arrangement the blocks
116 * 0-3 consists of page 0 + 4,1 + 5, 2 + 6, 3 + 7 Anyway JFFS2 would
117 * increase the eraseblock size so we chose a combined one which can be
118 * erased in one go There are more speed improvements for reads and
119 * writes possible, but not implemented now
