This patch adds support for 16 bit NAND devices attached to the
NDFC on ppc4xx processors. Two config entries were added:

  CONFIG_SYS_NDFC_16        - Setting this tells the NDFC that a
			      16 bit device is attached.
  CONFIG_SYS_NDFC_EBC0_CFG  - This is for the External Bus
			      Controller configuration register.

Also, a new ndfc_read_byte() function was added which does not
first convert the data to little endian.

The NAND SPL was also modified to do 16bit bad block testing
when a 16 bit chip is being used.

Add another nand write. variant, trimffs. This command will request of
nand_write_skip_bad() that all trailing all-0xff pages will be
dropped from eraseblocks when they are written to flash as-per the
reccommended behaviour of the UBI FAQ [1].

The function that implements this timming is the drop_ffs() function
by Artem Bityutskiy, ported from the mtd-utils tree.

Add a flag to nand_read_skip_bad() such that if true, any trailing
pages in an eraseblock whose contents are entirely 0xff will be
dropped.

The implementation is via a new drop_ffs() function which is
based on the function of the same name from the ubiformat
utility by Artem Bityutskiy.

This is as-per the reccomendations of the UBI FAQ [1]

When specified in the flags argument of nand_write, WITH_YAFFS_OOB causes an
operation which is mutually exclusive with the 'usual' way of writing.

Add a check that client code does not specify WITH_YAFFS_OOB along with any
other flags and add a comment indicating that the WITH_YAFFS_OOB flag should
not be mixed with other flags.

In a future commit the behaviour of nand_write_skip_bad()
will be further extended.

Convert the only flag currently passed to the nand_write_
skip_bad() function to a bitfield of only one allocated
member. This should avoid an explosion of int's at the
end of the parameter list or the ambiguous calls like

nand_write_skip_bad(info, offset, len, buf, 0, 1, 1);
nand_write_skip_bad(info, offset, len, buf, 0, 1, 0);

Instead there will be:

nand_write_skip_bad(info, offset, len, buf, WITH_YAFFS_OOB |
			WITH_OTHER);

For newer STM parts where CFI >= 1.1, there is a byte in the extended
structure that declares the flash layout type (just like the AMD parts),
so key off of that to find out when we need to reverse the geometry.

This can be seen with M29W640 parts where U-Boot does:
Bank # 1: CFI conformant FLASH (16 x 16)  Size: 8 MB in 135 Sectors
  AMD Standard command set, Manufacturer ID: 0x20, Device ID: 0x22ED
  Erase timeout: 8192 ms, write timeout: 1 ms
  Buffer write timeout: 1 ms, buffer size: 16 bytes

  Sector Start Addresses:
  20000000   RO   20002000   RO   20004000   RO   20006000   RO   20008000   RO

  ...

But Linux does:

i might be thinking of a different env_embedded situation.  a different
problem with your patch to tools/Makefile: you copied the same logic multiple
times which means more bitrot.

why dont you do something like:
