[Buildroot] Flash for AT91RM9200

[Samuelsson, Ulf <ulf.samuelsson@atmel.com>]

Hi you all!

I'm looking for a NOR-Flash for a RM9200-based board, and i thought 
maybe some of you could give some hints or experiences.
Basically it should be 128MByte size, with larger drop-in replacements 
as a favorable option. As with all RM9200 parallel flash, must have CFI, 
and must be available in a non-BGA package.
For a first guess, i found the Spansion S29G128P - any experiences with 
that one? How well is it supported by the kernel, or are there any 
obvious caveats that i overlooked now?

Greetz, Joe

=> The AT91RM9200 has 
     26 Adress pins (A0-A5)
     but A24 is nol  available.
     (See Errata)
     This gives you a 16 MB
     linear adressrange.
     Since A25 is available
     you can have 2 x 16 MB
     spaces with a 16 MB
     hole in between.

    However, I suspect that
    you only plan 128 Mbit
    and not 128 MByte
    and then this is not
    a problem
    
    If you are starting a design
    now,You should perhaps
    consider the AT91SAM9260
    or  the  AT91SAMG20
