72dec1666fe92b5a5932d7f5c26bdfc72e238bcb target/riscv: Apply modularized matching conditions for watchpoint
We have implemented trigger_common_match(), which checks if the enabled
privilege levels of the trigger match CPU's current privilege level.
Remove the related code in riscv_cpu_debug_check_watchpoint() and invoke
trigger_common_match() to check the privilege levels of the type 2 and
type 6 triggers for the watchpoints.
This commit also changes the behavior of looping the triggers. In
previous implementation, if we have a type 2 trigger and
env->virt_enabled is true, we directly return false to stop the loop.
Now we keep looping all the triggers until we find a matched trigger.
Only load/store bits and loaded/stored address should be further checked
in riscv_cpu_debug_check_watchpoint().
