Start to import support for the AArch64 architecture from ARM. This change
only adds support for kernel-toolchain, however it is expected further changes to add kernel and userland support will be committed as they are reviewed. As our copy of binutils is too old the devel/aarch64-binutils port needs to be installed to pull in a linker. To build either TARGET needs to be set to arm64, or TARGET_ARCH set to aarch64. The latter is set so uname -p will return aarch64 as existing third party software expects this.

# 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.
