Series refactor Kconfig to consolidate KEXEC and CRASH options | expand

Commit Message

Eric DeVolder July 6, 2023, 10:20 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
-	  you can start any kernel with it, not just Linux.

-	  Generate crash dump after being started by kexec. This should
