This board file enables the UART, USB and Ethernet interfaces as well as internal I2C and SDIO, and adds SoC voltage regulator and board-specific GPIO restart method info. Cc: Sam Lantinga Signed-off-by: Alexander Monakov --- At this point, major missing user-facing features are audio/video and power management (cpufreq, cpuidle, and/or suspend). It's easy to wire up the Vivante 3D graphics core, but without scanout it's not useful.
