Information about what SoC model, variant and version can be found in OTP. This series use this information in checkboard() to print out the running SoC model, variant and version.
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 v1 SoC: RK3566 v2 SoC: RK3566T v2 SoC: RK3568 v2 SoC: RK3568B2 v2 SoC: RK3568J v2 SoC: RK3582 v1 SoC: RK3588 v0 SoC: RK3588 v1 SoC: RK3588S v0 SoC: RK3588S v1 SoC: RK3588S2 v1 SoC: RK3308B SoC: RK3308B-S 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.
