It is not ideal for BL31 to continue to use boot console at runtime which could be potentially uninitialized. This patch introduces a new optional platform porting API `bl31_plat_runtime_setup()` which allows the platform to perform any BL31 runtime setup just prior to BL31 exit during cold boot. The default weak implementation of this function will invoke `console_uninit()` which will suppress any BL31 runtime logs. On the ARM Standard platforms, there is an anomaly that the boot console will be reinitialized on resumption from system suspend in `arm_system_pwr_domain_resume()`. This will be resolved in the following patch. NOTE: The default weak definition of `bl31_plat_runtime_setup()` disables the BL31 console. To print the BL31 runtime messages, platforms must override this API and initialize a runtime console. Fixes ARM-software/tf-issues#328 Change-Id: Ibaf8346fcceb447fe1a5674094c9f8eb4c09ac4a |
