This function is currently invoked in BL2 to flush this information to the next BL image, when LOAD\_IMAGE\_V2 is enabled. +Function : plat\_log\_get\_prefix() +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +:: + + Argument : unsigned int + Return : const char * + +This function defines the prefix string corresponding to the `log_level` to be +prepended to all the log output from ARM Trusted Firmware. The `log_level` +(argument) will correspond to one of the standard log levels defined in +debug.h. The platform can override the common implementation to define a +different prefix string for the log output. The implementation should be +robust to future changes that increase the number of log levels. + Modifications specific to a Boot Loader stage --------------------------------------------- |
