I'm unsure if OMAP ROM will be unhappy if the FAT partition is not at
the beginning.

The u-boot.imx really needs to be at offset 1KB on card to make imx51
ROM happy. Even I create the "non-FS data" partition from 0 cylinder
with sfdisk, it actually starts from sector 63 (offset ~ 32KB). We
can not really get the u-boot.imx into this partition for now.

This is something I'm not very clear. This bootcmd is written into
boot.scr which has to be loaded out from card first, in order to
launch the bootcmd. So we need to get "mmc init" executed before we
load fatload boot.scr.
Maybe it's an issue. The u-boot.imx "mmc init" is not working in this
case. I have to run "mmcinfo" before the first fatload, or it hangs.
