commit 92287c1a2afa93f2f20d2249827a57ffac6760c6
Author: Tim Newsome <ti...@si...>
Date: Thu Oct 27 15:21:31 2022 -0700
target: Add TARGET_UNAVAILABLE state
This is added for future RISC-V changes. The RISC-V debug interface can
explicitly tell a debugger when a hart is unavailable. This is used for
instance when that hart is powered down (or yet to be powered up out of
reset).
