From 571feed5b28fa9dda3e23fdc1f681e8037a544bd Mon Sep 17 00:00:00 2001 From: Eric DeVolder Date: Wed, 12 Jul 2023 12:15:39 -0400 Subject: mips/kexec: refactor for kernel/Kconfig.kexec 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.
