src/sys/external/bsd/vchiq/dist/interface/vchiq_arm:
vchiq_netbsd_acpi.c vchiq_netbsd_fdt.c
Log Message:
Do not attach vchiq(4) in big-endian mode.
For big-endian mode, all data written to and read from DMA buffer must be
byte-swapped. This requires heavy modifications to third party codes.
Also, we will switch to vc4 drm driver, hopefully soon.
