This device is one of several tablet models released in 2013 - 2014 based on Exynos 5420. The device tree added here contains support for: - UART - eMMC - SD card - USB CCI has been disabled in the hardware, enabling it would require (de-)soldering a resistor on the board. Trying to boot with it enabled in kernel makes the device hang when CCI is probed. Exynos5420-arndale-octa also has had CCI disabled due to issues [1]. To successfully boot the mainline kernel with the stock bootloader (SBOOT), an additional hack is needed [2]. The same hack is also needed to boot exynos4412-i9300 with stock bootloader, and probably other Samsung devices of similar age.

This device is one of several tablet models released in 2013 - 2014 based on Exynos 5420. The device tree added here contains support for: - UART - eMMC - SD card - USB CCI has been disabled in the hardware, enabling it would require (de-)soldering a resistor on the board. Trying to boot with it enabled in kernel makes the device hang when CCI is probed. Exynos5420-arndale-octa also has had CCI disabled due to issues [1]. To successfully boot the mainline kernel with the stock bootloader (SBOOT), an additional hack is needed [2]. The same hack is also needed to boot exynos4412-i9300 with stock bootloader, and probably other Samsung devices of similar age.
