Hi, I am working on a project that will need to be able to read/write the ID page of an EEPROM(currently a M95M02 SPI device from ST). From the code that I have seen, it seems that this chip is already supported, but there is no code to read/write the device ID page. I'm looking to add support, but I have some questions:
1. There are currently no IOCTLs defined for EEPROM devices, should I add a new IOCTL base or add an extra one to the MTD IOCTLs? 2. The default IOCTL for the EEPROM returns -ENOTTY which seems weird, should that be something else? 3. Since you could read/write the ID page, should this really be implemented as an IOCTL? I would assume that the functions would need to be more like the read/write syscalls where you pass in a buffer and the length(assuming you don't want to read or write the entire page). Would it make sense to make another node in /dev to access this page? -Robert Middleton
