Right - I changed the name back to be compliant with other phytec boards
in U-Boot, but I should improve the README - I ill do in V2.

On Phytec's website, the board is named (to be acquired) as
phyboard-mira. I will write in README that it is the same board, with a
link to Website.

Of course - I will fix it in the whole file.
