DOCBoot: "diskonchip" driver depreciated?

DOCBoot: "diskonchip" driver depreciated?

[Joseph M Dupre (AVAB Inc.)]

The DOCboot README refers to the kernel's diskonchip driver.

I am currently working with an un-patched 2.6.11.12 kernel.  It it 
there are drivers for Disk-On-Chip 2000 and various Millennium 
devices.  These are all marked depreciated.  Menuconfig help suggests 
to use the generic NAND device driver instead on the Disk-On-Chip 
driver.

Should this generic NAND driver work in conjunction with the DOCboot 
code and a "newer" DOC 2000 device?

I'm not tied to this kernel by any means, it is just what was current 
when I started.  But I _do_ need to get booting from the DOC 2000 
device and have not yet figured out how to do this.  I am using the 
DOC MD2202 series DIP on an i486 platform.

Thanks,

- Joe

There are more than one.  By referring in the README to the "diskonchip" 
driver, I mean specifically the driver that is *called* "diskonchip". 
(The parenthesized hint in step one about doing "modprobe diskonchip" is 
intended to make this clear).

I'll have to check the menuconfig wording, but what it should say is to 
use the new DOC driver that works *with* the generic NAND device layer, 
rather than the old DOC driver(s) that doesn't.  If you enable NAND 
support, you'll find this new driver.

Yes.

Should work fine; let me know if you need any more help.

Ah ha.  I had CONFIG_EXPERIMENTAL unset which prevented the new 
driver from showing up under NAND Flash Device Drivers.  I will carry 
on...
