snappy source files

[Swami]

Oliver,
Got it working. Modified the uboot.env.in to change the loadfdt variable as
in snappy-system.txt, and it loaded the fdt, followed by kernel boot
(pre-built) and went into snappy(initially tried in uboot environment
itself and loaded snappy step by step by running individual commands).
Success! Hope this is the right method of loading the fdt, as you said
snappy-system.txt is not used any more; but I still see it in the file
system of snappy after it boots up? Not sure. Anyways, will proceed with
other pieces of custom source like kernel, initrd, device tar ball and play
with it. Appreciate your help.

loadfdt=load mmc ${mmcdev}:${mmcpart} ${fdtaddr}
${snappy_ab}/dtbs/${fdtfile}
