> Hi Shelley, […]

So from looking at the code between MTK and QC, I think that ctrl_base == config_base.  Is that correct?  I don't have a preference on which name to use.  Let's just pick one.

Regarding atu_base and mmio_base....I feel like defining atu_base, mmio_base, mmio_size separately is more flexible than assuming that atu_base is config_base + 0x1000 and mmio_base is config_base + 0x100000.  I am, of course, assuming that these offsets can be different across different platforms.
