The kernel 5.10 and ti-sgx-ddk-km build know and I can create an image.

Now I still have two problems and need some advice what I'm doing wrong or how to fix these issues.

1.) The sgx section of my dts file is not recognized

&sgx {
status = "okay";
};

I got the error "Label or path sgx not found". In older version it was recognized.

2.) When booting with a dts without sgx section the created image SGX Kernel module is started and produced some errors
