[PATCH v3 00/21] plugin updates (register access) for 9.0 (pre-PR?)

[Alex Bennée]

Akihiko requested the register support not be merged in its current
state so it's time for another round of review. I've made a few tweaks
to simplify the register and CPU tracking code in execlog and removed
some stale API functions. However from my point of view its ready to
merge.

v3
--
  - split from testing bits (merged)
  - removed unused api funcs
  - keep CPUs in a GArray instead of doing by hand

v2
--

 - Review feedback for register API
 - readthedocs update
 - add expectation docs for plugins

The following still need review:

  contrib/plugins: extend execlog to track register changes
  gdbstub: expose api to find registers

Akihiko Odaki (15):
  hw/riscv: Use misa_mxl instead of misa_mxl_max
  target/riscv: Remove misa_mxl validation
  target/riscv: Move misa_mxl_max to class
  target/riscv: Validate misa_mxl_max only once
  target/arm: Use GDBFeature for dynamic XML
  target/ppc: Use GDBFeature for dynamic XML
  target/riscv: Use GDBFeature for dynamic XML
  gdbstub: Use GDBFeature for gdb_register_coprocessor
  gdbstub: Use GDBFeature for GDBRegisterState
  gdbstub: Change gdb_get_reg_cb and gdb_set_reg_cb
  gdbstub: Simplify XML lookup
  gdbstub: Infer number of core registers from XML
  hw/core/cpu: Remove gdb_get_dynamic_xml member
  gdbstub: Add members to identify registers to GDBFeature
  plugins: Use different helpers when reading registers

Alex Bennée (6):
  gdbstub: expose api to find registers
  plugins: add an API to read registers
  contrib/plugins: fix imatch
  contrib/plugins: extend execlog to track register changes
  docs/devel: lift example and plugin API sections up
  docs/devel: document some plugin assumptions
