did you see joachim's high priority task list?

it is bad enough that he likes blinkenlights :)  let's not dos him
with unnecessary complexity.

or do we think we are gonna learn something useful by putting a flash on
a noise board and make js have to drive it over that set of pins, which
i presume will be throw-away code?

that is my premise.  which is why i said that the novena has ram, use
it.  or, if we want flash and other toys, stick a board in the
micro-pcie slot where it will be on a 'normal' bus accessible to the
arm as well as the fpga, and in a 'normal' fashion.
