i am not sure this is a right place to use and not good at English please be generous
i am not good at linux ,
i read a wiki "STM32MP15 RAM mapping" and googled some information
i use kernel and u-boot from developerPackage
i have no plan to use M4 , so i like to give MCU sram to linux system
in device tree if i remove "no map" property in reseved memory's retram, mcuram,mcuram2 configuration and also remove m4_rproc's memory-region property is it enough ?
without no-map does MCURAM which has device tree with "compatible = "shared-dma-pool" be used as linux system shared-dma-pool ?
another question is from wiki 188.8.131.52.MCU SRAM4 i can't find example configuration in device tree, where could i get that ?
thank you sincerely
