| |
sama5d4_xplained has an optional on-board serial DataFlash (AT25DF321A), which does not come populated on board by default. Since the spi0 node does not have any child populated by default, thus no user on sama5d4_xplained, remove it. This avoids the following error in SPI NOR, which reads the values of the pulled downed lines, unrecognizing the flash:
spi-nor spi0.0: unrecognized JEDEC id bytes: 00 00 00 00 00 00
