Is it CFI-compliant? If so, it'll be at least detected by the current code. If it is capable of using the Intel command set, then it is supported. Otherwise, you will have a little bit of work to do to add support for it. It should be quite simple to add support for it if it doesn't support the Intel command set. First you need to provide a 'map' driver which allows access to the flash chips. Look at something simple like nora.c for an example - if your flash chips are mapped into virtual memory then all you need to do is change a couple of defines in nora.c to drive your own board. Then load the cfi_probe module and the nora module (or your own map driver). Show me all the output you get from it. -- dwmw2 To unsubscribe, send "unsubscribe mtd" to majordomo@infradead.org
