Intel P33 NOR flash with CFI revision 1.5

[Hamish Moffatt <hamish@cloud.net.au>]

Hi,

I have a new board with Intel P33 NOR FLASH which is reporting to have 
minor revision 5. The current driver refuses to deal with > 4.

I don't have any documentation on the new revision. However I hacked my 
source tree to allow version 5 and I can successfully read, erase and 
program the device. The kernel says:

IXP4XX-Flash.0: Found 1 x16 devices at 0x0 in 16-bit bank
IXP4XX-Flash.0: Found an alias at 0x800000 for the chip at 0x0
  Intel/Sharp Extended Query Table at 0x010A

Using buffer write method
cfi_cmdset_0001: Erase suspend on write enabled
erase region 0: offset=0x0,size=0x20000,blocks=63
erase region 1: offset=0x7e0000,size=0x8000,blocks=4

(It's an 8Mb part.)

Does anyone know any more about it?

thanks,
Hamish
