[Qemu-devel] [PATCH v2 00/31] target-xtensa: new target architecture

[Max Filippov]

This series adds support for Tensilica Xtensa target.
Port status: Linux for DC232B works in the qemu.
  Not implemented xtensa options: MAC16, floating point coprocessor,
  boolean option, cache option, debug option.

v1 -> v2 changes:
- extract PS register and access control into separate patch;
- implement all memory protection options;
- GDB support.
