Dear Thomas Gleixner,

I am an application engineer of the STMicroelectronics,
and I work in NAND Flash & Storage Media Division.

Now, I am working under Linux, in particular I am testing
ours NAND device with JFFS2 and YAFFS file system.
I have noted that, in the chiplist present in the file "nand_ids.h", miss some STMicro NAND chip supported from your code, and I would add it.

The STMicro NAND Flash chip to add are:

# NAND WITH SMALL PAGE
---------------------------
[1] 
  Name: "NAND 128MiB 1,8V 8-bit"
  Id:  0x39
  Pagesize:512
  Chipsize(in MByte):128
  EraseBlocksize:0x4000
  Options:0

[2]
  Name: "NAND 128MiB 1,8V 16-bit"
  Id:  0x49
  Pagesize:512
  Chipsize(in Mbyte):128
  Eraseblocksize:0x4000
  Options: NAND_BUSWIDTH_16
[3]
  Name: "NAND 128MiB 3,3V 16-bit"
  Id:  0x59
  Pagesize:512
  Chipsize(in MegaByte):128
  EraseBlocksize:0x4000
  Options: NAND_BUSWIDTH_16

# NAND WITH LARGE PAGE
-------------------------------

[1] 
  Name: "NAND 64MiB 1,8V 8-bit"
  Id:  0xA2
  Pagesize:0
  Chipsize(in MByte):64
  EraseBlocksize:0
  Options: NAND_SAMSUNG_LP_OPTIONS | NAND_NO_AUTOINCR

  Name: "NAND 64MiB 3,3V 8-bit"

Thanks in advance for your support.

Best Regards,
  Domenico
