How to Develop the ARM 64bit Board, Samsung TM2 with Exynos5433
summary
Samsung TM2 based on Exynos5433 runs Tizen 64-bit after a lengthy mainline upstreaming effort: roughly ~1,400 patches applied to the vendor tree and ~250 already posted to mainline. Work fixes 64-bit issues in compat ioctls, clock/regmap race and power-domain bugs, implements PSCI and HMP support on ARMv8, and uses runtime checkers KASAN and UBSAN to catch pointer and UB bugs. Resulting board boots userspace, runs hardware video decode and GPU demos (audio/modem remains proprietary).
