I'm not sure why 32 bits vs 64 bits matters here. We're going to share
a significant number of drivers already between armv7 and armv8, like
MMC, EMAC, I2C, and so on.

And I expect to share the data in other SoCs for the A10, A13 and A20
for example, or A23/A33, which have a lot of clocks in common too.
