The firmware is needed at radeon driver initialization time. When the driver is built into the kernel, this happens before the firmware can be loaded from userspace, so it needs to be built into the kernel as well.
ok, i find the solution, using radeon-ucode and CONFIG_DRM_RADEON=y , you have to change this on kernel to pass firmware on the fly on boot init.
CONFIG_STANDALONE=y # CONFIG_PREVENT_FIRMWARE_BUILD is not set CONFIG_FW_LOADER=y CONFIG_FIRMWARE_IN_KERNEL=y CONFIG_EXTRA_FIRMWARE=" radeon/CYPRESS_me.bin radeon/CYPRESS_pfp.bin radeon/CYPRESS_rlc.bin" CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware/"
thanks, you so much.
