To be more precise, I use ArmPlatformPkg/ArmVExpressPkg/ArmVExpress-RTSM-A15_MPCore.dsc to build the UEFI boot loader. This is from the tianocore EDK2 SVN repository.
I run this on the Fast Model simulator, simulating a examples/RTSM_VE/Build_Cortex-A15x2 board. My DTB is compiled from http://www.linux-arm.org/git?p=arm-dts.git;a=summary My kernel is from kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git Thanks for your help.

Yes, I use RTSM VE A15x2. I do not have real hardware, but I use the Fast Model simulator. By now I have read in the specs of arm.com that the Cortex-A15 test chip does not have TZ support. I was surprised, because the Cortex-A15 is v7 and supports the virtualization extensions, so according to the ARMv7 reference manual, it *must* also implement TZ. I guess the CPU on the board supports it, but it's just missing the TZ memory controller pieces. ----- Original Message ----- From: Olivier Martin <olivier.mar...@arm.com> To: 'Ryan Harkin' <ryan.har...@linaro.org>; Nicola Johnsen <nicolajohn...@yahoo.co.uk>; edk2-devel@lists.sourceforge.net Cc: Sent: Monday, 22 October 2012, 14:48 Subject: RE: [edk2] TrustZone support for VE Cortex A15? Thanks Ryan, that's a good point! I was trying to reproduce the issue with the kernel he sent me on RTSM VE A9x4 and I do not see the Linux decompression statement. In the last email Nicola sent me, it looks he is using RTSM VE A15x2. -----Original Message----- From: Ryan Harkin [mailto:ryan.har...@linaro.org] Sent: 22 October 2012 14:42 To: Nicola Johnsen; edk2-devel@lists.sourceforge.net Cc: Olivier Martin Subject: Re: [edk2] TrustZone support for VE Cortex A15? Olivier, Nicola is referring to the A15-TC1 BSP that's in my tree, not to the RTSM version...

As far as I could tell when I did the BSP for TC1, there was no TZ controller on that tile. Same with the A5 tile. If you're using TC1 hardware, you'll need some extra patches that I haven't pushed yet. I'm about to push a new version of my uefi-next tree [1] today. Withouth these small patches, the linux kernel is very unstable. Regards, Ryan.
