Information about what SoC model and variant can be found in OTP. This series use this information in checkboard() to print out the running SoC model and variant, should match what is printed on the SoC.
There are some asumptions taken on how some of the OTP values are encoded, however for my boards this seem to match and something like one of the following is shown with this applied: SoC: RK3566 SoC: RK3566T SoC: RK3568 SoC: RK3568B2 SoC: RK3568J SoC: RK3582 SoC: RK3588 SoC: RK3588S SoC: RK3588S2 SoC: RK3308B SoC: RK3308B-S Changes in v3: - Fix build issue with MISC=n or ROCKCHIP_OTP=n - Remove use of cpu-version - Use log_debug() instead of debug() Changes in v2: - Drop changes in generic-rk35xx_defconfig - Update code comments - Add patch for rk3308 This can probably be converted into an sysinfo driver in a future series, once other pending changes to sysinfo core have settled.
