Hell everybody,
I'm working with a board that has a ST M95320-R(http://www.st.com/internet/mcu/product/113067.jsp) EEPROM chip that works as a NVM for a Gigabit Ethernet card. This chip supports very basic subset of instructions (read/write, write enable/disable, read/write status word). Right now, in order to write the firmware to the chip I use custom tool that does only this task. And I think it would be much more convenient not to reinvent the wheel and just implement support of the said microchip in more generic open source tool such as 'flashrom'. But as far as I can tell, 'flashrom' is the tool built with flash memory solely in mind (24bit address assumption, erase +write cycle, etc.). So what I would like to know if 'flashrom' ever aimed to implement its functionality for aforementioned kind of chips? Is there any point for me to try to implement said functionality in the code-base?

hi andrey,
as expected no one replied so far... and you probably wont get another reply before after FOSDEM if at all. on the other hand this is also positive: no one was annoyed enough after reading the subject line to try to stop you ;)
flashrom was never intended to access EEPROMs, but on the other hand it was not designed to talk to other programmers than PC chipsets in the beginning either. it would be interesting to see where the problems lie and how far you could get. i would love to see patches for this purpose from you. but if you like to work on it i cant guarantee that it will be merged eventually of course. if you need any help just ask on IRC.
