Samsung's tablet Galaxy Tab S 10.5" (wifi) has codename chagallwifi and is one of several tablets released in 2013 - 2014 based on Exynos 5420. This initial devicetree adds support for accessing device over USB or UART, and allows using a rootfs in either the internal eMMC or an external sdcard. 4 out of 8 CPUs are brought up when device boots, which is the same as on the somewhat similar device exynos5420-arndale-octa. Patch 2 is necessary after a secure-firmware node is added, otherwise device hangs during the CPU1BOOT secure monitor call. Without the secure-firmware node we are not able to bring up any secondary CPUs.
