commit ab22b0bf8f23924d8c76d3affd9e11528ba18438
Author: Antonio Borneo <bor...@gm...>
Date:   Mon Nov 3 11:18:02 2025 +0100

    target: cortex-m: don't query cache on hla targets
    
    The cache handling code is written and optimized for dap queuing.
    On hla targets it causes a segmentation fault due to uninitialized
    AP pointer still set to NULL.
    
    While it's possible to modify the code to cope with hla targets,
    this would lower the OpenOCD performance on modern adapters.
    
    Make cache handling not available on hla targets.
