Pull request overview

Adds VX4 (VX4B-focused) support to the existing signal/profile MIPS measurement workflow, including target-specific app entrypoints, PLL init, and reference baselines so CI can profile mic-array MIPS on both XS3 and VX4.

Changes:

• Split MIPS reference baselines into per-platform JSON files and select them at test runtime based on tools version.
• Add VX4 implementations of the MIPS “burn”/“count” assembly routines plus a VX4B network main() and PLL initialization.
• Update CMake and Jenkins configuration to build with distinct XS3 vs VX4 tool selections.

File	Description
tests/signal/profile/test_measure_mips.py	Adds tool-version-based selection of ISR modes and reference JSON; adjusts logging/threshold.
tests/signal/profile/mic_array_mips_xs3.json	New XS3 baseline MIPS reference values.
tests/signal/profile/mic_array_mips_vx4.json	New VX4 baseline MIPS reference values (thread mode only).
tests/signal/profile/app_mips/src/mips/count_mips.S	Adds VX4 counter loop implementation.
tests/signal/profile/app_mips/src/mips/burn_mips.S	Adds VX4 burn loop implementation.
tests/signal/profile/app_mips/src/main.xc	Guards XC main() so it’s only compiled as XC.
tests/signal/profile/app_mips/src/main.c	Adds VX4B NETWORK_MAIN entrypoint.
tests/signal/profile/app_mips/src/app_pll.c	Adds VX4B PLL configuration; refactors XS3 PLL init behind app_pll_init().
tests/signal/profile/app_mips/src/app_config.h	Adds VX4B port mappings.
tests/signal/profile/app_mips/src/app.c	Switches from sw_pll_fixed_clock() to app_pll_init().
tests/signal/profile/app_mips/CMakeLists.txt	Makes build target-dependent (XS3 vs VX4) and limits ISR variants on VX4.
tests/signal/profile/app_memory/CMakeLists.txt	Removes deps.cmake include in favor of explicit dependent modules.
examples/app_mic_array_basic/vx4/device_pll_ctrl.c	Comment clarification for VX4 PLL divider settings.
Jenkinsfile	Splits XS3 vs VX4 tools parameters and tweaks build/test invocations.

looks great!! Sorry about the mips test :)
