[PATCH 5/5] bsps/stm32h7: allow config and usage of QSPI memory on stm32h747i-disco BSP

Karel Gardas karel at functional.vision
Fri Jun 10 12:49:30 UTC 2022


The QSPI memory is initialized and used only when the BSP configure file
sets QSPI memory size to non-zero value. Currently QSPI is run in memory
mapped mode which allows future RTEMS binary linkage and upload into QSPI
memory.
