/*
* U-Boot port for Turris Mox has a bug which always expects that "ranges" DT property
* contains exactly 2 ranges with 3 (child) address cells, 2 (parent) address cells and
- * 2 size cells and also expects that the second range starts at 16 MB offset. If these
+ * 2 size cells and also expects that the second range starts at 16 MB offset. Also it
+ * expects that first range uses same address for PCI (child) and CPU (parent) cells (so
+ * no remapping) and that this address is the lowest from all specified ranges. If these
* conditions are not met then U-Boot crashes during loading kernel DTB file. PCIe address
* space is 128 MB long, so the best split between MEM and IO is to use fixed 16 MB window
* for IO and the rest 112 MB (64+32+16) for MEM. Controller supports 32-bit IO mapping.
