[meta-freescale] MX28 Put u-boot on SPI NOR

[Mårten Wikman]

I did not erase memory before I typed write, maybe this is where it's
fails.
I'm using MX28EVK and I have added DNP resistors from schematics, without
them I could not get SPI NOR to work in linux. I'm going to test this
tomorrow morning and I will keep you updated, hopefully this solves it.
