<Grimler> Does anyone know if the bl1, bl2 and tzsw for exynos5420-arndale-octa can be downloaded somewhere (the company website seem to be permanently down)? I am curious if the tz fw actually handles the SMC_CMD_CPU1BOOT call that we run in arch/arm/mach-exynos/firmware.c when bringing up secondary CPUs. None of samsung's vendor kernels for exynos54xx uses this smc call, if I run it on my exynos5420 tablet
<Grimler> it hangs. For exynos5410-odroid-xu the tz fw has been reverse-engineered: https://github.com/hsnaves/exynos5410-firmware and it was found that SMC_CMD_CPU1BOOT isn't handled by the tz fw. Based on this I am guessing it is the same on all exynos54xx models, and that only exynos4 needs it
<Grimler> exynos5420-arndale-octa doesn't seem to hang on the SMC_CMD_CPU1BOOT call though (from Krzysztof's logs: https://krzk.eu/#/builders/32), unlike my tablet, so would be interesting to peek into the tz fw for this device and see if SMC_CMD_CPU1BOOT does anything
