I'm after adding some external parallel (i.e. no SPI or TWI) SRAM / FRAM to my NGW100.
The hardware side of things is not a problem (address / data bus, read / write / etc), as there's clear examples in the AVR32 datasheet on how to wire things up.
What I'm not sure about is the best (or rather easiest !!) way to add this sram device to linux ??
Do I have to write a whole new device driver that adds the sram to the /dev tree via sysfs ? If so, how ??
Or are there existing places I can hook the new device into so it (mgaically !!) appears without any extra effort ?
I'm guessing it's a whole new driver ... but feel free to steer me in the right direction !!
