This patch enables NAND subpage read functionality.

This significantly improves performance in many cases.

2008-07-11[MTD] [NAND] remove __PPC__ hardcoded address from DiskOnChip driversMilton Miller
Such a hardcoded address can cause a checkstop or machine check if the driver is in the kernel but the address is not acknowledged. Both drivers allow an address to be specified as either a module parameter or config option. Any future powerpc board should either use one of these methods or find the address in the device tree.

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. Also remove mtd->ecclayout and mtd->oobavail assignments, mtd core handles this all by itself.

2008-07-11[MTD] [NAND] fsl_elbc_nand: implement support for flash-based BBTAnton Vorontsov
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.

2008-07-11[MTD] [NAND] fsl_elbc_nand: fix OOB workability for large page NAND chipsAnton Vorontsov
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.

2008-07-11[MTD] [NAND] atmel_nand speedup via {read,write}s{b,w}()David Brownell
This uses __raw_{read,write}s{b,w}() primitives to access data on NAND chips for more efficient I/O. On an arm926 with memory clocked at 100 MHz, this reduced the elapsed time for a 64 MiB read by 16%. ("dd" /dev/mtd0 to /dev/null, with an 8-bit NAND using hardware ECC and 128KiB blocksize.) Also some minor section tweaks: - Use platform_driver_probe() so no pointer to probe() lingers after that code has been removed at run-time. - Use __exit and __exit_p so the remove() code will normally be removed by the linker. Since these buffer read/write calls are new, this increases the runtime code footprint (by 88 bytes on my build, after the section tweaks).
