Update Linux-CIP to kernel version 6.1

[diogo-ivo]

This pull request is an initial port to version 6.1 of linux-cip. Basic functionality seems to be working, including ethernet with the upstream version of the prueth driver. Some of the patches from 5.10 still need to be addressed, like EFI and some more advanced ethernet functionality.

We could move up to v6.1.54-cip6, then we would also have a corresponding -rt kernel.

What's the deal with that strange 2nd commit?

[jan-kiszka]

Ethernet is not working yet, driver does not bind to the device.

My Ethernet issue has been understood and resolved - firmware bug: https://patchwork.ozlabs.org/project/uboot/patch/aa0e6927-e35c-48b7-b3fb-785059f48910@siemens.com/

@diogo-ivo Any updates on this?

Just tested this in secure boot setup, and our reboot errors are back:

I don't get it yet, tee-supplicant is shut down and should have disconnected the fTPM driver, but there is still some command issued that fails in the absence of the supplicant daemon.

[jan-kiszka]

Shutdown issue resolved via optee-client patch in isar, see https://groups.google.com/g/isar-users/c/T5FuJo9A2hc.
