[MinnowBoard] Firmware hang

Hi Sjoerd,
   I had a similar problem on a minnowboard max.  I ended up replacing the
SPI flash part on it and that solved the problem.  Of course I probably
caused the problem by repeatedly programming the SPI flash with a 5v
programmer while I was working on UEFI driver development.  I don't remember
specifically where the boot would hang but repeated power cycling the board
would get it too boot eventually.  The problem started out happening
occasionally and slowly got worse until I had to power cycle many times to
get a good boot.

I used part # N25Q064A11ESE40G as the replacement.  Here is a link to Arrow
where I purchased them.

Hope this helps.
