The problem with the eepromer directory is that it's a mess. There are 3 tools there which do basically the same (programming EEPROMs), but each has its own limitations: * eeprom can't deal with 16-bit addressed EEPROMs nor SMBus-only controllers. * eepromer can't deal with 8-bit addressed EEPROMs nor SMBus-only controllers. * eeprog only uses SMBus byte/word reads and writes, it lacks support for raw I2C block writes so it is slow on large EEPROMs. On top of that, eeprom and eepromer build with a lot of warnings. I really don't want to maintain 3 different tools with the same purpose. eeprog seems to be the most promising of all 3, as it is fully functional, but I don't feel comfortable dropping the other 2 until block write support is added to eeprog. Would you be interested in adding block write support to eeprog? It has been on my to-do list for a long time but I could never find the time to actually look into it. I do not use these tools myself so my personal interest is low and this is why it never makes it to the top of my to-do list. > Signed-off-by: Matwey V.

I'd rather only integrate eeprog, so that distributions ship only that and everybody uses only that. Maybe eeprog should be moved to its own directory, and that new directory would be integrated into the build system while the rest of the eepromer directory would be left alone (and ultimately deleted.) -- Jean Delvare SUSE L3 Support -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
