Hi Tarek,


And I reproducibly get failures for CPUs 1-3, resulting in only one CPU
in /proc/cpuinfo (compared to 4 on downstream 3.14):

I also notice another apparent device tree issue:

[    7.341814] of_get_named_gpiod_flags: can't parse gpios property of
node '/soc/mmc at 12220000/slot at 0[0]'
[    7.341850] of_get_named_gpiod_flags: can't parse gpios property of
node '/soc/mmc at 12220000/slot at 0[0]'

Are any of those known issues and being worked on?
(The CPU failures affected 5420 Arndale Octa as well iirc.)

Can you check after applying following two patches for Arndale-Octa
([1],[2])? In other words, a patch similar to [2] might be required
for this board too if it is booting under secure mode.

Firmware node already present into exynos5410-smdk5410.dts
So with only patch[1] 4xA15 cores will boot on ODROID-XU and SMDK5410.

I also confirm that with 4xA15 cores boot when adding patch [1].
