The series of patches represent support of Exynos 5410 SoC
The Exynos 5410 is the first Samsung SoC based on bigLITTLE architecture
Patches allow all 8 CPU cores (4 x A7 and 4 x A15) to run at the same time
Patches add new platform description, support of clock controller,
dual cluster support and device tree for Exynos 5410
Has been build on v3.12.
Has been tested on Exynos 5410 reference board (exynos_defconfig).
I've applied the patches on top of today's linux-next and tried to boot
my ODROID-XU using exynos5410-smdk5410.dts and exynos_defconfig, but all
I can get is an imprecise external abort, when the kernel tries to jump
to init. Full boot log below. Any ideas?
Best regards,
Tomasz

Tomasz, there is CCI on/off switcher on smdk5410 board, also there is
XOMCCI pin on SoC.
Looks like switcher on board controls the XOMCCI SoC pin.
When I turn switcher OFF, I getting the same problem you got.
Please, check the cci state on Odroid-XU Board, maybe it is turned off.
Best regards,
Tarek Dakhran
