fsl_elbc_nand: ecclayout cleanups

2008-09-12T19:58:33Z

This patch deletes oobavail assignments, they're calculated by the nand core code in nand_scan_tail, plus current oobavail values are wrong for the LP NANDs. Signed-off-by: Anton Vorontsov Signed-off-by: David Woodhouse Signed-off-by: Scott Wood

fsl_elbc_nand: implement support for flash-based BBT

2008-09-12T19:57:20Z

This patch implements support for flash-based BBT for chips working through ELBC NAND controller, so that NAND core will not have to re-scan for bad blocks on every boot. Because ELBC controller may provide HW-generated ECCs we should adjust bbt pattern and bbt version positions in the OOB free area.

fsl_elbc_nand: fix OOB workability for large page NAND chips

2008-09-12T19:56:03Z

For large page chips, nand_bbt is looking into OOB area, and checking for "0xff 0xff" pattern at OOB offset 0. That is, two bytes should be reserved for bbt means. But ELBC driver is specifying ecclayout so that oobfree area starts at offset 1, so only one byte left for the bbt purposes. This causes problems with any OOB users, namely JFFS2: after first mount JFFS2 will fill all OOBs with "erased marker", so OOBs will contain: OOB Data: ff 19 85 20 03 00 ff ff ff 00 00 08 ff ff ff ff OOB Data: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff OOB Data: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff OOB Data: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff And on the next boot, NAND core will rescan for bad blocks, then will see "0xff 0x19" pattern, and will mark all blocks as bad ones. To fix the issue we should implement our own bad block pattern: just one byte at OOB start. Though, this will work only for x8 chips. For x16 chips two bytes must be checked. Since ELBC driver does not support x16 NANDs (yet), we're safe for now. Signed-off-by: Anton Vorontsov Signed-off-by: David Woodhouse Signed-off-by: Scott Wood

Fix printf errors under -DDEBUG

2008-09-09T22:02:41Z

Fix printf format-string/arg mismatches under -DDEBUG. These warnings occur with DEBUG defined for a platform using cpu/mpc85xx. Users of other architectures can unearth similar problems by adding the line "CFLAGS += -DDEBUG=1" in config.mk right after "CFLAGS += $(call cc-option,-fno-stack-protector)".
