Im too lazy to go look at the data sheet, so i will skip 1)

My mind reading capabilities is also off line,  so i will skip 2) as well.

Flash v2 makes this easy. Just register both drivers. The flash
infrastructure will run the probe function to see if the flash
actually exist. So you would expect one to fail to probe and one to
work. The flash infrastructure will then direct all operations through
the working driver.
