The Tenstorrent Atlantis platform is a collaboration between Tenstorrent
and CoreLab Technology. It is based on the Atlantis SoC, which includes
the Ascalon-X CPU and other IP from Tenstorrent and CoreLab Technology.
The Tenstorrent Ascalon-X is a high performance 64-bit RVA23 compliant
RISC-V CPU.
Add the tt-atlantis machine containing serial console, interrupt
controllers, and device tree support.
The Atlantis boot images loaded from include OpenSBI and an initial DTB
that is passed to OpenSBI. This is approximated in the model by having
QEMU build the device tree rather than load a DTB image directly.
Subsequent stages may use the modified DTB provided by OpenSBI or opt to
supply their own.
