pxa3xx: NAND chip initial reset

Hi,

On my PXA300 based system, I'm facing a problem with a recent Micron NAND chip which needs to get a reset command to make it wake up initially. The pxa3xx_nand.c does not seem to do this.

I've seen a post[1] from October 2008 which addresses exactly this issue, but the mentioned commit (in the follow-up) does not fix it for me. I did some print tracing and the generic code path is not entered because the platform driver's probe routine returns with an error. Before I dig into all the mtd code, I'd like to ask whether anyone can come up with a simple idea of how to do this.

Thanks,
Daniel
