Hello all, This is my first post here or any mailing list, so my apologies for any mistakes.
I have added board support for the Embest Marsboard based on the imx6 dual core chip. Embest do provide an old version of U-Boot ( 2009.08-svn8 ). Using the current git master branch and the Wandboard and Boundry Nitrogen6x and the original Marsboard files I have a working U-Boot. Both the eMMC and SD card and SPI flash environment appear to be working. I seem to have problems with networking, but have discovered the same problem with the original U-Boot so could be my network cable. Here are the changes from the current git master.
