Hi Andrey
Can you include a new topic to linux-linaro which contains device-tree files for ARM's fast models? This branch is tracking-armlt-rtsm [1] in the ARM LT working tree.
Thanks
For those interested...
These device-trees enable the the current Linaro vexpress kernel to boot on fast-models when used with the boot-wrapper at [2], this includes having a working display. However, on the big.LITLE models the A7 cores don't start, giving "Failed to boot -38".
Does that bootwrapper do anything to bring the A7s out of reset? I think by default they are held in reset -- there is a model configuration parameter for that, but I can't remember it off-hand. For the in-kernel switcher, we have hacks in the bootwrapper to bring the A7s out of reset instead.
