SubjectRe: [PATCH 0/3] nvmem: eeprom: add support for FRAM
Date
Hi Jiri,

I have two Fujitsu different FRAMs running with the stock at25 driver. I set
the page size equal to the device size (as FRAMs have no pages).

Are you able to run your FRAM with the unmodified driver?

I assume that getting the device geometry from the chip is vendor specific (in
contrast to flash devices which have standard commands for this). I suppose
that there is no much value getting vendor specific information from a chip. If
the drivers knows the vendor, it should also know the chip (e.g. from the dt).

regards
Christian
