Summary: R/W on BF527 Nand hangs

Details:

Doing R/W (cp, touch...) on yaffs on BF527 Nand would hang. This is also reported on 2008R1.5. : blackfin.uclinux.org/gf/project/uclinux-dist/forum/?action=ForumBrowse&_forum_action=MessageReply&message_id=68044

Looks like bug in NFC driver.

Looks to me, hangs at

bf5xx_nand_dma_rw(): wait_for_completion(&info->dma_completion)

DMA irq may never happen.

Fixed now,The DMAs have different size on BF52x and BF54x.
