Sorry that I haven't been able to follow up on why that doesn't work,
and what the real fix would be (if it's not this one). Every time I
see people discussing terms like CD, RESETn and PDn, I simply get lost
(and such discussion seems to originate only from Marvell).

Are these generic SD/MMC terms that I simply don't understand, or are
we talking Marvell specific terminology that I'm not alone in lacking
understanding of?

Thanks,
Daniel
