[Antony Pavlov <antonynpavlov@gmail.com>]

Antony Pavlov (9):
  RISC-V: make it possible to run nmon from PBL C code
  RISC-V: boards: erizo: make it possible to use nmon
  serial: add litex UART driver
  gpio: add driver for 74xx-ICs with MMIO access
  spi: add litex spiflash driver
  net: add LiteEth driver
  RISC-V: add initial LiteX SoC support
  RISC-V: add litex-linux board support
  RISC-V: add litex_linux_defconfig
