[U-Boot] what are flash settings for Spansion 4M S29AL032D flash?

a couple of us have been fighting with this for a couple hours ... we have an old powerpc board on which we've hacked u-boot to get to the prompt, now we're trying to get u-boot to recognize that flash chip.

at u-boot time, u-boot prints both the manufacturer ID and device as "0x0" so, clearly, it's not picking that up properly. can anyone suggest what the proper u-boot configuration selections should be for that particular flash?
