Series refactor Kconfig to consolidate KEXEC and CRASH options | expand

Commit Message

Eric DeVolder July 12, 2023, 4:15 p.m. UTC 
The kexec and crash kernel options are provided in the common
kernel/Kconfig.kexec. Utilize the common options and provide
the ARCH_SUPPORTS_ and ARCH_SELECTS_ entries to recreate the
equivalent set of KEXEC and CRASH options.

-	  kexec is a system call that implements the ability to shutdown your

-	  but it is independent of the system firmware.   And like a reboot

-	  The name comes from the similarity to the exec system call.

-	  It is an ongoing process to be certain the hardware in a machine

-	  initially work for you.  As of this writing the exact hardware
-	  interface is strongly in flux, so no good recommendation can be
