gen_probe -> (etc) -> qry_present failing on MVME5100

[jglennon at getntds.com]

Am working on MTD on PowerPC:
target board:   Motorola MVME5100, CPU=MPC750
                FLASH = 4x AMD29D323D, is CFI.

kernel:  2.2.4 (Hard Hat Linux 2.0)
MTD:     CVS download of about Tuesday (10/30/01)

It appears like the command to enter CFI Query mode not working; subsequent
cfi_reads return "normal" flash data, I think.  So qry_present returns 1.

I say it looks like normal FLASH contents because I see the stuff cfi_read
returns when I use PPC_BUG6> m 0xF4000000 and scroll on down to ...80 which
is 0x10 * osf.

I am likely missing something basic.  Like incorrect xconfig settings!
Help appreciated!

Enclosed is .config.
Thank you!
