The SBI v2.0 specification is now frozen. The SBI v2.0 specification defines
SBI debug console (DBCN) extension which replaces the legacy SBI v0.1
functions sbi_console_putchar() and sbi_console_getchar().
(Refer v2.0-rc5 at https://github.com/riscv-non-isa/riscv-sbi-doc/releases)

This series adds support for SBI debug console (DBCN) extension in
Linux RISC-V.

[...]

Here is the summary with links:
  - [v5,1/5] RISC-V: Add stubs for sbi_console_putchar/getchar()
    https://git.kernel.org/riscv/c/f503b167b660
  - [v5,2/5] RISC-V: Add SBI debug console helper routines
    https://git.kernel.org/riscv/c/f43fabf444ca
  - [v5,3/5] tty/serial: Add RISC-V SBI debug console based earlycon
    https://git.kernel.org/riscv/c/c77bf3607a0f
  - [v5,4/5] tty: Add SBI debug console support to HVC SBI driver
    https://git.kernel.org/riscv/c/88ead68e764c
  - [v5,5/5] RISC-V: Enable SBI based earlycon support

You are awesome, thank you!

Nathan points out that this has some semantic conflicts with a patch in
Greg's TTY tree: https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git/commit/?id=f32fcbedbe9290565e4eac3fd7c4c451d5478787

So I think the best bet is to wait on Greg's patch to land in Linus'
tree, and then base a v6 of this patch set on that merged patch.  I'm
going to drop this one from for-next.

Greg's patch is now available in upstream Linux so I will rebase and
send out v6.

Sorry, I forgot about this one and merged it.  I just sent up a fixup: 
https://lore.kernel.org/all/20240119215612.20529-2-palmer@rivosinc.com/ (local) 
.

Thanks,
