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

[Marek Vasut]

Dear Mårten Wikman,

I dunno about the Yocto ML, but usually you don't want to be top-posting in the 
ML.

Yes, that is likely. You can also use ' sf update ', which is less abbrasive for 
the flash (it first reads the SF, then does erase+write cycle only if the block 
changed). But for the first installation of u-boot, use erase + write manually 
to make sure everything is written correctly.

OK. Make sure that you can even write the SF correctly in the first place.
