The Pine64 exposes both controllers on the PI-2 and Euler connectors. Tested/verified with logic analyser and spidev_test using MOSI/MISO loopback. Note: spi0 on the A64 may conflict with the eMMC controller, as the MISO pin is also used for the HS400 eMMC data strobe. This is only a concern if the board uses eMMC (does not apply to the Pine64) *and* is using HS400 mode. The same pin conflict exists for the H5.
