Hello Andy,

Thanks for your patch, I applied it after adjusting some small things.
See below.

This last line was indented with spaces instead of a tab. This was
pointed out by "make check-package":

I wasn't a big fan of including the full arm/ directory, because while
it for now only contains this GPU firmware, it might contain other
things in the future. Since the panthor driver loads this:

        snprintf(fw_path, sizeof(fw_path), "arm/mali/arch%d.%d/%s",
                 (u32)GPU_ARCH_MAJOR(ptdev->gpu_info.gpu_id),
                 (u32)GPU_ARCH_MINOR(ptdev->gpu_info.gpu_id),
                 CSF_FW_NAME);

I changed linux-firmware.mk to this:

LINUX_FIRMWARE_FILES += arm/mali/arch*/mali_csffw.bin

so that it only installs the CSF firmware.

Applied with those changes. Thanks!

Thomas
