ARV7510PW22, ARV752DPW and ARV752DPW22 have the RT2860 eeprom stored in flash as big-endian, but the driver needs it in little-endian format. We have to swab it before handing it over. This requires my earlier patch for busybox. Funnily enough, ARV752DPW works also with the incorrect eeprom, but undoubtedly unoptimally. I have a hunch that also the final remaining Lantiq board would require this swabbing, but I'm not sure, so I just swab it in the three boards that I know about. v2: * Swab also on ARV7510PW22 based on feedback from Alvaro Rojas * Fix the offset with bs=2 Signed-off-by: Matti Laakso <malaakso at elisanet.fi> SVN-Revision: 40328
