From 66e6a43818734a2423dcfcd5bf52a33df86e89aa Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Thu, 12 Aug 2021 10:33:44 +0100 Subject: hw/arm/stm32f405: Wire up sysclk and refclk Wire up the sysclk and refclk for the stm32f405 SoC. This SoC always runs the systick refclk at 1/8 the frequency of the main CPU clock, so the board code only needs to provide a single sysclk clock. Because there is only one board using this SoC, we convert the SoC and the board together, rather than splitting it into "add clock to SoC; connect clock in board; add error check in SoC code that clock is wired up". When the systick device starts honouring its clock inputs, this will fix an emulation inaccuracy in the netduinoplus2 board where the systick reference clock was running at 1MHz rather than 21MHz.
