commit bedefa238476ad852b1fafd927230e38e2092282
Author: Samuel Obuch <sam...@es...>
Date:   Wed Aug 19 07:45:45 2026 +0200

    target/xtensa: flush cached registers before starting an algorithm
    
    In case any aX registers are already dirty, modifying arY registers
    for the algorithm run will cause these values to be lost. Resolve
    inconsistencies in xtensa_write_dirty_registers, so that registers
    do not have to be re-fetched from the target.
