- Add subpage write support
- Add onenand_oob_64/32 ecclayout
This has been missing and without it UBI has some incompatibilies issues
with the current (>= 2.6.27) Linux kernel version. vid_hdr_offset is
placed differently (2048 instead of 512) without this fix.

The version (ver_id) was not stored in the onenand_chip structure and
because of this the continuous locking scheme could be enabled on some
chips.

This brings the core NAND code up to date with the Linux kernel.
Since there were several drivers in Linux as of the last update that are
not in u-boot, I'm not bringing over new drivers that have been added
since in the absence of an interested party.
I did not update OneNAND since it was recently synced by Kyungmin Park,
and I'm not sure exactly what the common ancestor is.

Since page size field is changed from oobblock to writesize. But OneNAND is not updated.
- fix bufferram management at erase operation
This patch includes the NAND/OneNAND state filed too.

onenand_print_device_info():
- Now returns a string to be placed in mtd->name,
rather than calling printf.
- Remove verbose parameter as it becomes useless.

The block and page parameters of onenand_verify_page() are not used. This causes a compiler error when CONFIG_MTD_ONENAND_VERIFY_WRITE is enabled.

This is particularly problematic now that non-NAND-specific code is
including <nand.h>, and thus all debugging code is being compiled
regardless of whether it was requested, as reported by Scott McNutt
<smcnutt@psyent.com>.

Onenand needs a version of memcpy() which performs 16 bit accesses
only; make sure the name does not conflict with the standard
function.
Signed-off-by: Wolfgang Denk <wd@denx.de>
It should access with 16-bit instead of 8-bit
Now it uses the generic memcpy with 8-bit access. It means it reads wrong data from OneNAND.

Flex-OneNAND is a monolithic integrated circuit with a NAND Flash array
using a NOR Flash interface. This on-chip integration enables system designers
to reduce external system logic and use high-density NAND Flash
in applications that would otherwise have to use more NOR components.
Flex-OneNAND enables users to configure to partition it into SLC and MLC areas
in more flexible way. While MLC area of Flex-OneNAND can be used to store data
that require low reliability and high density, SLC area of Flex-OneNAND
to store data that need high reliability and high performance. Flex-OneNAND
can let users take advantage of storing these two different types of data
into one chip, which is making Flex-OneNAND more cost- and space-effective.
