This package is picorv32 soc, including HW and SW parts
HW parts
1. cliffordwolf's picorv32_wb with some modifications
  (1) add read strobe signal, for WB 8-bit device access (opencore's uart16550)
  (2) add timer reload mechanism, timer will automatically reload
  (3) add global irq disable/enable mechanism for RTOS porting (a new picorv32_ctlirq_insn)
2. wb_intercon, Wishbone bus matrix
3. opencore's uart16550
4. wishbone SRAM
5. Simulation environment, currently only support Cadence ncsim
6. FPGA
  Support the following FPGAs
  (1) BeMicro CV-A9 (already phased-out on www.arrow.com)
  (2) Intel Stratix V Advanced Systems Development Kit Special Edition (with 2x 5sgxeabn2f45c2n chip)
  (3) FPGA 530 (https://fpgatry.world.taobao.com)
  (4) Xilinx xc7k325t (https://item.taobao.com/item.html?id=556680465917)

SW parts
1. Toolchain, please refer to https://github.com/cliffordwolf/picorv32
2. boot code (boot from SRAM)
3. FreeRTOS porting (boot from SRAM)
