At present that patch breaks at least one x86 board and I have not dug into it yet.
The revert should not break tegra, according to Stephen.
Unfortunately, my testing on P2571 with TOT u-boot-tegra (rebased against TOT u-boot/master this morning) shows that that is not true.
The revert of the disputed 'fdtdec_get_addr_size' patch _does_ break Tegra 64-bit (P2571, at least). Nyan-big is OK. With Simon's revert in place, my board just loops on SPL signon, so I assume it's faulting, etc. in CPU init. Note that this is the current state of TOT u-boot/master.
I'm a bit confused. So far, we don't support SPL on T210 since we assume some other bootloader runs on the boot CPU and starts just the main U-Boot on the main CPU. It sounds like you're testing some local-only SPL support?
