But I see the point of confusion... Instead of teaching
"SDHCI core" to work with 32 bits hosts, we'd better handle this
in the eSDHC part, in the accessors.

This is relatively trivial and should not cause much overhead
(at least when using DMA), just a small state machine with
the xfer mode register shadowed in software (plus, notice that
this also handles BLOCK_SIZE, as I promised in another email):

Me like. Keeps my life a lot saner. :)

Just be aware that there is a remote risk of breakage as people hacking
on sdhci-core won't be aware of esdhc's, let's call it unique,
behaviour. Some testing now and then on your part would be prudent. :)
