However, on some devices it instead causes the device to hang, so let's avoid the call for the SoCs where it should not be needed. To see that the call is ignored, we can look into sboot/tzsw. On most of the Exynos{4,5} devices the part of sboot/tzsw that seem to handle the secure monitor calls is quite easy to recognise, the SMC number is compared to known ones, and if equal it branches to the relevant function. In assembly this looks something like: ;-- handle_smc: 0x00000514 650070e3 cmn r0, 0x65 0x00000518 0a00000a beq loc.smc_cmd_reg 0x0000051c 010070e3 cmn r0, 1 0x00000520 6c00000a beq loc.smc_cmd_init 0x00000524 020070e3 cmn r0, 2 0x00000528 6b00000a beq loc.smc_cmd_info 0x0000052c 030070e3 cmn r0, 3 0x00000530 6e00000a beq loc.smc_cmd_sleep 0x00000534 060070e3 cmn r0, 6 0x00000538 ae00000a beq loc.smc_cmd_save_state 0x0000053c 070070e3 cmn r0, 7 0x00000540 b400000a beq loc.smc_cmd_standby 0x00000544 2b01001a bne loc.smc_return_minus1 where above example is from exynos5420-arndale-octa. As can be seen the case where r0 is 4 (i.e. SMC_CMD_CPU1BOOT) is not handled. The annotations are taken from github.com/hsnaves/exynos5410-firmware, where a large part of the exynos5410 trustzone firmware has been reverse-engineered.

This device is one of several tablet models released in 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, see commit 25217fef3551 ("ARM: dts: disable CCI on exynos5420 based arndale-octa").
