commit 606f8efbb8eee2094421ee00941ac38a9a507a47

    tcl/target: Add support for Nordic nRF54L series
    
    The RISC-V coprocessor is currently not supported. It is attached to the
    DAP via AP#2 but the AP implementation is unknown.
    
    The nRFL54L series uses resistive RAM (RRAM) as non-volatile memory
    which can be programmed directly. Since it does not fit in the current
    flash memory infrastructure of OpenOCD there is no NVM support so far.
