thanks for all the replies!

I tried using PIO-only, which didn't help.

But then I saw our SDHCI driver was using a disable-multiblock-io-quirk.
Upon removing that, it magically fixed the issue :)

Now it boots fine and I just scanned the area for wifi networks (haven't 
tried connecting to one, since I couldn't figure out iw{config,list}), 
which worked.

Thanks,
