+config PHYSICAL_START
+ hex "Physical address where the kernel is loaded" if (EXPERT || CRASH_DUMP)
+ default MEMORY_START
+ ---help---
+ This gives the physical address where the kernel is loaded
+ and is ordinarily the same as MEMORY_START.
+
+ Different values are primarily used in the case of kexec on panic
+ where the fail safe kernel needs to run at a different address
+ than the panic-ed kernel.
