+ * QEMU RISC-V Board Compatible with SiFive E300 SDK
+ *
+ * Copyright (c) 2017 SiFive, Inc.
+ *
+ * Provides a board compatible with the bsp in the SiFive E300 SDK:
+ *
+ * 0) UART
+ * 1) CLINT (Core Level Interruptor)
+ * 2) PLIC (Platform Level Interrupt Controller)
+ * 3) PRCI (Power, Reset, Clock, Interrupt)
+ * 4) Registers emulated as RAM: AON, GPIO, QSPI, PWM
+ * 5) Flash memory emulated as RAM
+ *
+ * The Mask ROM reset vector jumps to the flash payload at 0x2040_0000.
+ * The OTP ROM and Flash boot code will be emulated in a future version.
