Hi all,

This is an implementation of IBM client architecture (CAS) reboot for GRUB.

There are cases where the POWER firmware must reboot in order to support specific features requested by a kernel. The kernel calls ibm,client-architecture-support and it may either return or reboot with the new feature set. eg:

Calling ibm,client-architecture-support.../
Elapsed time since release of system processors: 70959 mins 50 secs
Welcome to GRUB!

Instead of return to the GRUB menu, it will check if the flag for CAS reboot is set. If so, grub will automatically boot the last booted kernel using the same parameters
