From 712bd17f3e6c5b33ad1e33661350164c9f8468bf Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Thu, 12 Aug 2021 10:33:38 +0100 Subject: [PATCH] armsse: Wire up systick cpuclk clock Wire up the cpuclk for the systick devices to the SSE object's existing mainclk clock. We do not wire up the refclk because the SSE subsystems do not provide a refclk. (This is documented in the IoTKit and SSE-200 TRMs; the SSE-300 TRM doesn't mention it but we assume it follows the same approach.) When we update the systick device later to honour "no refclk connected" this will fix a minor emulation inaccuracy for the SSE-based boards.
