| parent | sh: Make SH7786 PCIe port reset logic more aggressive. (diff) | |

sh: Establish a SuperHyway<->PCIe window mapping on SH7786 PCIe.
This bumps up the low address to match the physical memory windows for
SHway<->PCIe transfers. The previous implementation was banking on a 1:1
virt<->phys SHway mapping, which doesn't apply here.
