Hello,

this series adds support for memory protection unit, parity/ECC option
and IDMA and gather/scatter IRQ types. With these additions it is possible
to emulate basic opcode subset of the recent xtensa LX vision cores.

Max Filippov (5):
  target/xtensa: get rid of centralized SR properties
  target/xtensa: make internal MMU functions static
  target/xtensa: define IDMA and gather/scatter IRQ types
  target/xtensa: add parity/ECC option SRs
  target/xtensa: implement MPU option
