Oh well. I hope he's not disappointed by having had to change this twice.

We'll see how it works out. I don't think a conversion to decivolts of
already checked in code makes sense now, and I'd say we close this issue
until we have serious problems with the size of the flashchip support
table. My constification patch provided a 99% reduction for the .data
section, so the immediate effect of a flashchip array shrink would only
hit .rodata which is less of an issue.
