RE: ML507 EDK 10.1

Hi John Linn,

Yes I have dowloaded the linux_support.tar.gz.
So if I get you correct I will use the bit stream provided by
linux_support.tar.gz clubbed with the zImage to create Ace file, I hope
that should work Ace file should boot the kernel. correct me if I am
wrong. Let create it and test it

As for ML403 we created zImage.dts and clubbed it with bit stream and
created ace file it botts up fine.

Thanks in Advance
Neelu
