[MTD] [OneNAND] 2X program support

2007-06-30T07:24:57+00:00

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

[MTD] [OneNAND] Classify the page data and oob buffer

2007-03-09T08:08:09+00:00

Classify the page data and oob buffer
and it prevents the memory fragementation (writesize + oobsize)

[MTD] OneNAND: Reduce internal BufferRAM operations

2007-02-02T00:29:36+00:00

It use blockpage instead of a pair (block, page). It can also cover a small chunk access. 0x00, 0x20, 0x40 and so on.

And in JFFS2 behavior, sometimes it reads two pages alternatively.
e.g., It first reads A page, B page and A page.
So we check another bufferram to find requested page.
