ARM Trusted Firmware (low level Secure World software) - Myth busters

Less than one minute read time.

If you didn't make it to the Linaro Connect in Macau earlier this month you may have missed Andrew Thoelke's excellent pitch on ARM Trusted Firmware.  ARM Trusted Firmware is low level, highly privileged Secure World software architected for ARM v8A.   ARM has been developing it as open source code with a permissive licence so that anyone developing Secure World software can use it as a reference implementation.  You can get it here:

ARM-software/arm-trusted-firmware · GitHub

Andrew did the talk in a "Myth busting" style to explain what ARM Trusted Firmware is and dispel some common misconceptions.  You can see the video here:

http://people.linaro.org/linaro-connect/lca14/videos/03-03-Monday/LCA14-102-%20Adopting%20ARM%20Trusted%20Firmware.mp4

And the slides here:

http://www.linaro.org/documents/download/5d6b29bf365401256850c4e35c3dd8075314a195ee748

ARM Trusted Firmware was developed on our v8A Fixed Virtual Platform Models which you can download from our website.   This work should be relevant to anyone who wants to develop trusted software: for example Trusted Execution Environment developers, Silicon Partners, OEMs etc.

What do you think of Andrew's myth busting pitch?   Was it helpful?  Did you have another question?
