The CPU complex reset masks are not matching with the datasheet for the CLK_RST_CONTROLLER_RST_CPU_CMPLX_SET/CLR_0 registers. For both T20 and T30 the register consist of groups of 4 bits, with one bit for each CPU core. On T20 the 2 high bits of each group are always stubbed as there is only 2 cores.
This looks correct to me. Given this problem, it's surprising that reset_A9_cpu() was operating correctly, and that secondary CPUs were coming out of reset OK later. What testing has this had (which SoCs and boards)?
I only tested it on T30 using our Tamonten NG board.
OK, I tested on all Tegra SoCs, and everything (including a CPU hotplug test in a kernel once booted with the new U-Boot) still works, so,
