Apparently the NanoPi K2 (Amlogic S905) is also susceptible to the ATF allocation fault on mainline. Patch fixes issue, K2 now boot to desktop and does not crash due to memory-intensive activities.
Amlogic changed memory location of firmware, patch fixes that issue. Appears to fix the kernel crash on Le Potato, needs more testing.
