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. > > [1] http://www.spinics.net/lists/linux-samsung-soc/msg31776.html > > [PATCH v2 Resend 1/2] ARM: EXYNOS: Update secondary boot addr for secure mode > > [2] http://www.spinics.net/lists/linux-samsung-soc/msg31777.html > > [PATCH v2 Resend 2/2] ARM: dts: Add secure firmware support for Arndale-octa > > > -- > Tushar Behera Best regards, Tarek -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
