144 * U-Boot port for Turris Mox has a bug which always expects that "ranges" DT property
145 * contains exactly 2 ranges with 3 (child) address cells, 2 (parent) address cells and
146 * 2 size cells and also expects that the second range starts at 16 MB offset. Also it
147 * expects that first range uses same address for PCI (child) and CPU (parent) cells (so
148 * no remapping) and that this address is the lowest from all specified ranges. If these
149 * conditions are not met then U-Boot crashes during loading kernel DTB file. PCIe address
150 * space is 128 MB long, so the best split between MEM and IO is to use fixed 16 MB window
151 * for IO and the rest 112 MB (64+32+16) for MEM, despite that maximal IO size is just 64 kB.
152 * This bug is not present in U-Boot ports for other Armada 3700 devices and is fixed in
153 * U-Boot version 2021.07. See relevant U-Boot commits (the last one contains fix):
154 * https://source.denx.de/u-boot/u-boot/-/commit/cb2ddb291ee6fcbddd6d8f4ff49089dfe580f5d7
155 * https://source.denx.de/u-boot/u-boot/-/commit/c64ac3b3185aeb3846297ad7391fc6df8ecd73bf
156 * https://source.denx.de/u-boot/u-boot/-/commit/4a82fca8e330157081fc132a591ebd99ba02ee33
157 * Bug related to requirement of same child and parent addresses for first range is fixed
158 * in U-Boot version 2022.04 by following commit:
159 * https://source.denx.de/u-boot/u-boot/-/commit/1fd54253bca7d43d046bba4853fe5fafd034bc17
