[MTD] [NAND] Blackfin on-chip NAND Flash Controller driver
This is the driver for latest Blackfin on-chip nand flash controller - use nand_chip and mtd_info common nand driver interface - provide both PIO and dma operation - compiled with ezkit bf548 configuration - use hardware 1-bit ECC - tested with YAFFS2 and can mount YAFFS2 filesystem as rootfs ChangeLog from try#1 - use hweight32() instead of count_bits() - replace bf54x with bf5xx and BF54X with BF5XX - compare against plat->page_size in 2 cases when enable hardware ECC ChangeLog from try#2 - passed nand_test suites - use cpu_relax() instead of busy wait loop - some coding style issue pointed out by Andrew Signed-off-by: Bryan Wu <bryan.wu@analog.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
