We are about to bring up a new board and just realized that booting from a SD Card isn't quite as straight forward as we thought. We didn't design in SPI Flash but have a uSD card connected to MMCSD0 and for production we plan on booting from a 8-bit NAND connected to EMA_D[0-7].
If I'm reading the correct pages it seems that new silicon should support booting from an SD Card but I'm a little confused on the procedures to make a card that has U-Boot, Linux Kernel, and File System on the card. Is there a pre-made image available that I can download and test? It certainly would be nice to eliminate 1 variable when bringing up the brand new board.
