Hello,
I add some debug information to the radeon-source-code of linux-kernel,then I rebuild kernel and update kernel（the compiled driver is called A, and the original driver is called B ）
①If I add the radeon/CAICOS_xx.bin to CONFIG_EXTRA_FIRMWARE in.config file ，during kernel startup, the radeon driver executed is B（The serial port can not print the debug information I added ）， and the display-monitor can be bright。
①If kept CONFIG_EXTRA_FIRMWARE empty ，during kernel startup, the radeon driver executed is A（The serial port can print the debug information I added ）， and the display-monitor is not bright。
Why？
