I'm talking about lib/logic_pio.c here - commit 031e3601869c ("lib: Add generic PIO mapping method") introduced this. In fact, logic pio will override these for arm64 with the vanilla defconfig these days. It seems that your change was made just after that logic pio stuff went into the kernel. Thanks, John
