[PATCH v1 00/20] gdbstub, semihosting and test/tool updates (pre PR)

[Alex Bennée]

Hi,

This is gathering together my maintainer trees into one place in
advance of putting together a pull request next week. There are:

  - gdbstub: more tests and tweaks to SVE handling for ARM
  - semihosting: common code and enabling for RiscV
  - some minor test and devtool tweaks

Last chance to object to any of the changes ;-)
