Ca. 30% of the "presumed identical" IP blocks in R-Car Gen3 SoCs turned out not to be that identical...

That was an early judgment error, which we regret making. Initially, R-Car H3 ES2.0 (r8a77951) was assumed to be a slightly improved variant of R-Car H3 ES1.x (r8a77950), while it turned out to be a completely different SoC.
