Sean Anderson a7c81fc853 riscv: Add Sipeed Maix support ... The Sipeed Maix series is a collection of boards built around the RISC-V Kendryte K210 processor. This processor contains several peripherals to accelerate neural network processing and other "ai" tasks. This includes a "KPU" neural network processor, an audio processor supporting beamforming reception, and a digital video port supporting capture and output at VGA resolution. Other peripherals include 8M of sram (accessible with and without caching); remappable pins, including 40 GPIOs; AES, FFT, and SHA256 accelerators; a DMA controller; and I2C, I2S, and SPI controllers. Maix peripherals vary, but include spi flash; on-board usb-serial bridges; ports for cameras, displays, and sd cards; and ESP32 chips. Currently, only the Sipeed Maix Bit V2.0 (bitm) is supported, but the boards are fairly similar. Documentation for Maix boards is located at <http://dl.sipeed.com/MAIX/HDK/>. Documentation for the Kendryte K210 is located at <https://kendryte.com/downloads/>. However, hardware details are rather lacking, so most technical reference has been taken from the standalone sdk located at <https://github.com/kendryte/kendryte-standalone-sdk>.
