+ * 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
+ * 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, despite that maximal IO size is just 64 kB.
+ * This bug is not present in U-Boot ports for other Armada 3700 devices and is fixed in
+ * U-Boot version 2021.07. See relevant U-Boot commits (the last one contains fix):
+ * https://source.denx.de/u-boot/u-boot/-/commit/cb2ddb291ee6fcbddd6d8f4ff49089dfe580f5d7
