IEC binary prefixes ease code review: the unit is explicit.
Add a comment describing the Connex uses a Numonyx RC28F128J3F75
flash, and the Verdex uses a Micron RC28F256P30TFA.
Correct the Verdex machine description (we model the 'Pro' board).

This patch is doing somewhat more than the commit Subject line
suggests. I don't think it's particularly strongly in need
of splitting into more patches, but could you make the
subject line a bit closer to what the patch is doing?

Previously the variable names were helpfully acting as a
bit of documentation of what the 64MB and 16MB things were.
Perhaps we could instead have
#define CONNEX_ROM_SIZE (16 * MiB)
#define CONNEX_RAM_SIZE (64 * MiB)
and then use those?
