This patch is the one bisecting will end up with when somebody
uses an older SDMA firmware or the ROM scripts. It should have a
better description what happens and what should be done about it.

Emm..That's true. Timeout will be caught in such case, hence,
maybe we can

fall back it to pio always.

With my patch applied sdma_load_context() will fail. I don't know
how exactly this hits into the SPI driver, but it won't be a timeout.

Thanks for your quick test, assume you use ROM firmware, right?

Yes.

Would you please have a try with the attached patch which is based this patch set?
