Start support for the RISC-V 64-bit architecture developed by UC Berkeley.
RISC-V is a new ISA designed to support computer research and education, and is now become a standard open architecture for industry implementations. This is a minimal set of changes required to run 'make kernel-toolchain' using external (GNU) toolchain. The FreeBSD/RISC-V project home: https://wiki.freebsd.org/riscv.

# This file specifies various information about terminals on the system.

# It is used by several different programs. Common entries for the

# various columns include:
|

#
|
||||
# name The name of the terminal device.
|
||||
#
|
||||
# getty The program to start running on the terminal. Typically a
|
||||
# getty program, as the name implies. Other common entries
|
||||
# include none, when no getty is needed, and xdm, to start the
|
||||
# X Window System.
|
||||
#
|
||||
# type The initial terminal type for this port. For hardwired
|
||||
# terminal lines, this will contain the type of terminal used.
|
||||
# For virtual consoles, the correct type is typically xterm.
|
||||
# Other common values include dialup for incoming modem ports, and
|
||||
# unknown when the terminal type cannot be predetermined.
|
||||
#
|
||||
# status Must be on or off. If on, init will run the getty program on
|

# the specified port. If the word "secure" appears, this tty
