I need some information about trustzone

Note: This was originally posted on 19th July 2013 at http://forums.arm.com

Hello there everyone,
Greetings!

I am Partho Paul, from India, Chennai. and I am here for some information. And this also happens to be my first post in the arm.com forums.
And my english is broken with loads and loads of grammar and spelling mistakes. kindly forgive me of those errors.

I will not try to beat around the bush, but this is what I am trying to do and this is my plan.
I am planning to port coreboot (www.coreboot.org) to blackberry playbook, which is omap4430 HS device. Which i plan to showcase in the GSOC14.
I have gathered most of the info regarding how to xloader and u-boot and etc etc.

Now I have a little confusion. First off I need some information about jtag and how do I proceed. I think, I have found the jtag pin outs and this Sunday I will give a try with jtag.
So now here is my real question. can I program the trusted zone?

If I understand correctly then the volatile SRAM holds the UUID and RSA metadata and SHA256 sum.

Can someone point me where am I making a blunder and help me from not doing a suicidal blunder. What should be my proper approach?

The arm documents says using proper tools i can modify the secure areas but i want to know which proper tools.
I got a wiggler jtag and buspirate to do the debugging and now how do i proceed. this will be my first question.

And my second question will be, how do i reprogram the efuse. Because the arm documents said i can reprogram the efuse. and there are loads of information there like SPIDEN and SPNIDEN and SUIDEN and SUNIDEN. and there is this secure_boot_lock can be set to 0 = low and 1 = high.

How do i do it in real life?

Because too much information got me a little lost.

I am not doing this for financial gain because i wish to be in the GSOC 2014, since all my proposals till date been rejected. Can someone please help me?

thanks!
