  riscv: dts: Add DT support for SiFive FU540 GPIO driver (2020-01-29 14:58:08 +0000)

----------------------------------------------------------------
RISC-V Patches for the 5.6 Merge Window, Part 1

This tag contains a handful of patches that I'd like to target for this merge
window:

* Support for kasan.
* 32-bit physical addresses on rv32i-based systems.
* Support for CONFIG_DEBUG_VIRTUAL
* DT entry for the FU540 GPIO controller, which has recently had a device
  driver merged.

These boot a buildroot-based system on QEMU's virt board for me.

----------------------------------------------------------------

      kasan: No KASAN's memmove check if archs don't have it.
      riscv: Add KASAN support
      kasan: Add riscv to KASAN documentation.

Olof Johansson (1):
      riscv: keep 32-bit kernel to 32-bit phys_addr_t
