128Mbit SPI flash uses
#1
Is the SPI flash programmed at the factory with necessary boot code, or is that just there for us to use in our own applications? It looks like the PINE64 has an EMMC instead of a SPI flash and Linux-SunXI wiki says SPI-flash has a lower boot priority than SD-Card, so I'm assuming it's presently unused.

If it's available for us to use without breaking the boot process, we're thinking we might store device specific calibration values there rather than on the SD-Card. Has anyone played around with the SPI flash yet? From the above SunXI page I get the feeling that drives might not yet be in the kernel.
