Reg RIFF Tool support.

[Venkat Raghavulu]

Hi Benn,

Thanks for the information.

I will did check the page for details. I did understand it.

Meanwhile, can you please confirm me if my understanding of problem is
correct, so that I donot go and confuse engineers at Linaro and there by
not get the required support.
The following is the my understanding of the problem to flash Linaro ICS on
eMMC using the RIFF tool:
a. Snowball boards require secure booting boot code.
b. Creating the ToC and packing of the secure code is done by the script
file do_image.py, which produces an .img file. RIIF tool flashes this .img
file.
c. Linaro tools can create the .img file which can be used by RIFF tool to
flash it on an eMMC device.
d. The problem now being, Linaro tool does not have provision to include
the secure boot files "*.sw" while it creates the .img file.

Thanks and Regards,
Venkat.
