#### YamlPlugin
This plugin offers a service to other plugins to generate a useful Yaml file describing the CPU configuration. It contains, for instance, the sequence of instructions required

/**
* This an example of VexRiscv configuration which can run the official RISC-V debug.
* You can for instance :
* - generate this VexRiscv
* - cd src/test/cpp/regression
* - make IBUS=CACHED IBUS_DATA_WIDTH=64 COMPRESSED=no DBUS=CACHED DBUS_LOAD_DATA_WIDTH=64 DBUS_STORE_DATA_WIDTH=64 LRSC=yes AMO=yes DBUS_EXCLUSIVE=yes DBUS_INVALIDATE=yes MUL=yes DIV=yes SUPERVISOR=yes CSR=yes RVF=yes RVD=yes DEBUG_PLUGIN=RISCV WITH_RISCV_REF=no DEBUG_PLUGIN_EXTERNAL=yes DEBUG_PLUGIN=no VEXRISCV_JTAG=yes
*
* This will run a simulation of the CPU which wait for a tcp-jtag connection from openocd.
* That con connection can be done via openocd :
* - src/openocd -f config.tcl
*
* Were config.tcl is the following :
*
* ##############################################
* interface jtag_tcp
* adapter speed 5000
*
* set _CHIPNAME riscv
* jtag newtap $_CHIPNAME cpu -irlen 5 -expected-id 0x10002FFF
*
* set _TARGETNAME $_CHIPNAME.cpu
*
* target create $_TARGETNAME.0 riscv -chain-position $_TARGETNAME
*
* init
* halt
*
* echo "Ready for Remote Connections"
* ##############################################
