According to the PL310 TRM, 0 in the latency fields(setup/read/write) indicates 1 cycle of latency for Tag and Data RAM latency control registers. If we want to set 1 cycle of latency, we need to clear the field actually. The TRM is as below: https://developer.arm.com/documentation/ddi0246/h/programmers-model/register -descriptions/tag-and-data-ram-latency-control-registers Signed-off-by: Haifeng Li <haifeng...@timesintelli.com> drivers/cache/cache-l2x0.c | 6 ++++++ 1 file changed, 6 insertions(+)
