What should value of CONFIG_MTD_CFIB* be?

[Subodh Nijsure <subodh@best.com>]

[I am very much a novice when it comes flash..] 

In the latest MTD code ( from infradead CVS ) there are few #defines 
are introduced CONFIG_MTD_CFI_B1, B2,B3 and CONFIG_MTD_CFI_I1. 


What should my values be for above variables 
if my hardware is two Intel 28F160S3
(sector size 64K) flash devices, configured to operate in 
16-bit mode giving me 4Mb, 32-bit wide memory? 


This is how my MTD config looks like and cfi_probe is not able to  
detect these intel chips.

p.s.
In my bootrom I have command called flashcfi where I have 
code, I am able to read Q R Y when I send READ QUERY command 00980098 

Retrieve cfi info assuming flash base is BASE0=0X28000000
In function flash_retrieve_cfi_info
Clear any status register info Writing @0x28000000 value 00500050
Put flash into READ ID mode Writing @0x28000000 value 00900090
Put flash into READ QUERY mode Writing @0x28000000 value 00980098
Reading at 28000040 value 'Q'
