This simulate various OneNAND flash chips for the MTD onenand layer.
It's simple implementation, only basic operations.
It don't support the recent changes in NANDSIM such as lazy block allocation,
bitflip, and so on.
Note: This passed nand-tests.

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
Now the following chips support it. (KFXXX16Q2M)
Demux: KFG2G16Q2M, KFH4G16Q2M, KFW8G16Q2M,
Mux: KFM2G16Q2M, KFN4G16Q2M,
And more recent chips

Use menuconfigs instead of menus, so the whole menu can be disabled at once
instead of going through all options.

Now the bootloader configures the OneNAND sync. burst mode.
So we don't access Sync. burst mode related registers in kernel.

One Block of the NAND Flash Array memory is reserved as
a One-Time Programmable Block memory area.
Also, 1st Block of NAND Flash Array can be used as OTP.
The OTP block can be read, programmed and locked using the same
operations as any other NAND Flash Array memory block.
OTP block cannot be erased.
OTP block is fully-guaranteed to be a valid block.
