[Qemu-devel] [PATCH v5 00/32] 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, cache option, debug option.

v4 -> v5 changes:
- implement boolean option;
- fix v4 stylistical issues (underscores, comparison order, missing braces);
- turn WINDOWBASE_BOUND and WINDOWSTART_BIT macros into inline functions;
- convert sample boards to memory API.
