[MTD] OneNAND: Reduce internal BufferRAM operations 2007-02-02T00:29:36+00:00 Kyungmin Park kyungmin.park@samsung.com 2007-02-02T00:29:36+00:00 abf3c0f23df6686a984efc8fae7277fcdaffaa32 It use blockpage instead of a pair (block, page). It can also cover a small chunk access. 0x00, 0x20, 0x40 and so on. And in JFFS2 behavior, sometimes it reads two pages alternatively. e.g., It first reads A page, B page and A page. So we check another bufferram to find requested page. Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>
