The AFU Descriptor Template in the PCI config space has a Name Space field which is a 24 Byte ASCII character string of descriptive name space for the AFU. The OCXL driver read the string four characters at a time with pci_read_config_dword(). This optimization is valid on a little-endian system since this is PCI, but a big-endian system ends up with each subset of four characters in reverse order. This could be fixed by switching to read characters one by one. Another option is to swap the bytes if we're big-endian. Go for the latter with le32_to_cpu().
