Having the rootfs stored on SPI NOR is a poor design decision as you're
better of with a NAND, which is cheaper and faster on writes. I tried in
the past a ubifs on top of a large (64 and 128MB) SPI NOR flash. But
they were plug-able flashes, not something that is always tied to the
board. Microchip's sama7g5ek comes with a 128MB macronix SPI NOR flash
populated. But there are other vendors that provide large SPI NORs if
really needed.
