Subject: [PATCH v2 11/22] verification/rvgen: Prepare the templates for LTL inclusion
To prepare for the inclusion of linear temporal logic monitor, prepare the
generation template files:
- Rename the directory dot2k_templates to templates
- Move the dot2k-specific files to templates/dot2k
- Move the container-specific files to templates/container
(Kconfig can be shared with LTL, therefore leave it at templates/)
This new structure allows sharing code for reading Kconfig and main.c
templates between DA monitor, container monitor and LTL monitor.
The intention is to add template files for LTL to templates/ltl.
Signed-off-by: Nam Cao <namcao@...utronix.de>
