Also it 143 * expects that first range uses same address for PCI (child) and CPU (parent) cells (so 144 * no remapping) and that this address is the lowest from all specified ranges. If these 145 * conditions are not met then U-Boot crashes during loading kernel DTB file. PCIe address 146 * space is 128 MB long, so the best split between MEM and IO is to use fixed 16 MB window 147 * for IO and the rest 112 MB (64+32+16) for MEM, despite that maximal IO size is just 64 kB. 148 * This bug is not present in U-Boot ports for other Armada 3700 devices and is fixed in 149 * U-Boot version 2021.07.
