The 2X Program is an extension of Program Operation.
Since the device is equipped with two DataRAMs, and two-plane NAND Flash
memory array, these two component enables simultaneous program of 4KiB.
Plane1 has only even blocks such as block0, block2, block4 while Plane2
has only odd blocks such as block1, block3, block5.
So MTD regards it as 4KiB page size and 256KiB block size

Here it's not the case: all the entries are occupied by
OOB chunks. Therefore, once we get into a loop like
for (free = this->ecclayout->oobfree; free->length; ++free) {
}
we might end up scanning past the real oobfree array.
Probably the best way out, as the same thing might happen for common NAND
as well, is to check index against MTD_MAX_OOBFREE_ENTRIES.
