This series adds support for SBI debug console extension in KVM RISC-V
and Linux RISC-V.

To try these patches with KVM RISC-V, use KVMTOOL from riscv_sbi_dbcn_v1
branch at: https://github.com/avpatel/kvmtool.git

These patches can also be found in the riscv_sbi_dbcn_v1 branch at:
https://github.com/avpatel/linux.git

Anup Patel (5):
  RISC-V: Add defines for SBI debug console extension
  RISC-V: KVM: Change the SBI specification version to v2.0
  RISC-V: KVM: Forward SBI DBCN extension to user-space
  tty/serial: Add RISC-V SBI debug console based earlycon
  RISC-V: Enable SBI based earlycon support

Atish Patra (1):
  tty: Add SBI debug console support to HVC SBI driver
