based device. Following u-boot commands allow FreeBSD boot on Yiyate Android TV Box (aml8726-m3): tv open 480p mmc rescan 0 fatload mmc 0 0x80100000 kernel.bin go 0x80100000 The current FreeBSD driver doesn't program the video clocks so the u-boot tv command is necessary in order for the frame buffer to be useful (otherwise it can be skipped). The SD card for the Yiyate Android TV Box doesn't need anything special beyond creating a FAT16 and a UFS filesystem. Differential Revision: https://reviews.freebsd.org/D2636 Submitted by: John Wehle
