[PATCH v3 00/10] RISC-V: add LiteX SoC support; resurrect nmon

[Antony Pavlov <antonynpavlov@gmail.com>]

Changes since v2:

  * rebase on top of master branch (f873c7ff2497) +
    "RISC-V: extend multi-image to support both S- and M-Mode"
    (http://lists.infradead.org/pipermail/barebox/2021-May/036086.html).
  * "litex serial: add setbrg callback" patch by Marek Czerski is added
    for review;
  * fix "clocksource: timer-riscv: select CSR from device tree" patch;
  * change gpio IP-block base addresses in litex dts;
  * gpio-74xx-mmio uses device_get_match_data() now.

Changes since v1:

  * rebased on top of next branch;
  * new patches are introduced:
    * clocksource: timer-riscv: select CSR from device tree
    * RISC-V: make RISCV_SBI and RISCV_M_MODE explicitly mutually exclusive
    * RISC-V: make it possible to build RV32I multi-image with DEBUG_LL=n
  * almost all of Ahmad's notes are fixed (e.g. unused header files inclusions are dropped);
  * NOT FIXED: gpio-74xx-mmio still uses dev_get_drvdata(), not device_get_match_data()

Antony Pavlov (9):
  clocksource: timer-riscv: select CSR from device tree
  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 LiteX SoC and linux-on-litex-vexriscv support
  RISC-V: add litex_linux_defconfig

Marek Czerski (1):
  litex serial: add setbrg callback
