Is there potentially more than one part used on the Jetson nano as I get the following on mine:

Loading Environment from SPI Flash... unrecognized JEDEC id bytes: 00, 40, ff
[Tom] No, just the Macronix 4MB part. You probably need the VI_I2C fix, there was a problem with the index of the internal_id table. The Macronix part is JEDEC C2, 25, 36 IIRC.
See "i2c: t210: Add VI_I2C clock source support", just posted a few days ago, should be in tegra-next.
