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
2000A000 RO 2000C000 RO 2000E000 RO 20010000 RO 20020000 RO
...
But Linux does:
physmap platform flash device: 00800000 at 20000000
physmap-flash.0: Found 1 x16 devices at 0x0 in 16-bit bank.
Manufacturer ID 0x000020 Chip ID 0x0022ed

When dealing with non-multipoint devices, if the software root hub code
accepted the message, then we still need to process it normally. So only
return quickly when the root hub skipped the message or is otherwise in
an error state.

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:

mkimage relies on autogenerated version so we need to move
$(VERSION_FILE) rule out of ifeq and make tools rule depend on it to be
able to run 'make tools' from the unconfigured tree.

LDSCRIPT is used only from the top-level Makefile and only when the
system is configured so we can move LDSCRIPT and CONFIG_SYS_LDSCRIPT
related logic into the top level Makefile and under configured condition
to avoid errors when building tools from unconfigured tree.
